Don’t get me wrong. The Deluxe Reverb is a great amp. But the Fenders I love pretty much all fall in the tweed era, where there wasn’t a ton of great headroom and you got into a nice snarl pretty early in the sweep of the volume knob.

1960's Kay 507 Twin Ten Vintage Guitar Amp

You don’t see a bunch of the dual 6V6 single 12” Kays. The models you tend to see the most are the little (and somewhat anemic) single-ended practice amp, the 703. And the Kay tube amp you tend to see the least is the VERY cool duel 6L6 (sometimes) Kay 507 Twin Ten.

1960's Kay 507 Twin Ten Vintage Guitar Amp

As the name suggests, the amp pushes two (ALNICO) 10” speakers powered by a pair of 6L6’s. What’s weird is that a LOT have 7868’s as output tubes and use a 7199 in the circuit. 7868’s have a great tone, in general. They are, from what I’ve read, essentially the same tube as a 7591, but with nine pins instead of eight. 7199’s got used a lot in Ampegs and Sanos and they are very rare and they aren’t made anymore, so they tend to cost a lot of dough. So, buyer beware (especially about the 7199) on this amp. BUT, the model I have has what are obviously original 6L6’s and no rare or obscure preamp tubes (five 12AX7’s do the preamp and phase inverter jobs) and the old stand-by 5U4 for rectification. Mine is all original—as the schematic inside matches what’s in the amp. But there seem to have been some variations on the construction of the 507—so, ask the seller about/check the tubes when buying so you know what your 507 has in it.

1960's Kay 507 Twin Ten Vintage Guitar Amp

Also, it’s one of the coolest looking amps you’ll see. It has two channels (two inputs per channel), a VERY snazzy chrome rear control panel with six knobs (tone and volume for each channel and speed and intensity for the tremolo). And it has a very 50’s-looking two tone appearance (even though it lists that they were made 1960-1963), brown rear and light brown front with a white swirl on brown cloth grill. It’s a great size—not too heavy and 24” wide by 20” tall.

1960's Kay 507 Twin Ten Vintage Guitar Amp

OK, it looks cool, but how does it sound? Pretty freaking cool. It sounds a lot like the other great Chicago amps of the same period. And this is where things get kind of interesting—who made these Kay amps? It has a tone very much like the great Valcos (which ended up branded, at various times, Supro, Airline and, in the 400 series, Harmony). And, like a Valco, it has a tone a bit like some of the great Lectrolabs, too (I’ve seen Lectrolabs branded under their own name and also with Philharmonic and the 300 series of Harmony amps). But, it’s not made by either Valco or Lectrolab (I get this info from a friend of mine who knows more about off-brand amps than anyone I know and has a collection to prove it). It also doesn’t look like a Valco or Lectrolab under the hood. It’s simply made differently (though it is point-to-point like both of those brand—no hand stuffed circuit board like on a Tweed Fender). According to my friend, it was Kay who actually made these Kay amps over these years (go figure). As I say, this friend knows a lot more than me and has written several books on the Chicago giants. Plus, it’s easy to tell from looking that it wasn’t made by Valco or Lectrolab. So, if it isn’t easy to tell who DID make it, at least we know who DIDN’T.

1960's Kay Dual 6V6 Vintage Guitar Amp

Whoever made it, though, it’s a wonderful amp. At low volume, you get a VERY rich and textured clean sound. The two ten inch speakers sound great and the cleans are very complex, much like a Tweed Fender Super from the early 50’s. This is one of the richest, thickest (without being overly dark) cleans I have ever heard in a vintage amp. And when you add the tremolo, wow! It moves from a VERY slow, pulsing tremolo, to a pretty fast one—but it never gets totally choppy and helicopter-sounding like a lot of the late 60’s tremolos. Throughout the range of the “strength” control, the tremolo stays watery and smooth. Just a killer sound.

1960's Kay Dual 6V6 Vintage Guitar Amp

Turned up, it sounds more like a 6V6 amp than most 6L6 amps I’ve ever heard. Very Neil Young and Crazy Horse. If you push the volume on the channel you’re using to 6 or higher, it starts to really snarl and have a complex great sounding distortion. The volume and tone controls are interactive, too, so you can get some very nice textures of distortion by either coupling the channels with a short cord, or just playing with the volume of the channel you’re not using. Open it up full and put the other channel around 5 or 6 and it sounds VERY much like Neil Young’s tone on RAGGED GLORY—that opening of “Country Home” sounds spot on when this amp is cranked.

1960's Kay Dual 6V6 Vintage Guitar Amp

It’s a sleeper. And there don’t seem to be too many of them out there. I haven’t heard the 7868 output tube version of this amp, but I’d sure like to. In any case, if you see one of the 507 Twin Tens with 6L6 output tubes, I’d buy it in a heartbeat. I’m doing a MAJOR purge around here—selling at least five guitars and five amps. And I kept going back and forth on the Kay 507. Then I plugged it in to write this and I decided I’d be nuts to get rid of it. There simply aren’t that many of them. And I don’t want to feel like I felt about letting go of my 4X6V6 Danelectro Challenger with a 15 inch speaker. That was another super rare amp I let go of, and I still get angry at myself. From now on, I’ve vowed to only get rid of stuff I could easily replace if I truly regretted the sale. So this one stays.

Vintage 1960's Guyatone GA-530A Guitar Amplifier

Japanese-made tube amps from the 60’s represent, in general, one of the great values left in the vintage market. Frequently, you can pick up little combos like this Guyatone (or the Univox U-45B) for under $300. Real vintage tube tone for under $300 (and frequently even lower)? What’s not to love?

This Guyatone, along with coming cheaply and sounding great, is a looker. In white Tolex (or Tolex-like material), this is a stunning looking amp that was a popular model (though not for export) in the Mid-60’s Japanese “Group Sounds” movement. A great amp for chiming Beatles-inspired sounds or tremolo-drenched surf-styled instrumentals, the GA-530A is one to keep your eyes peeled for. It’s a classy looking amp, and one that probably looked just fine gracing the stage of the 60’s Japanese TV show Kachinuki Eleki Gassen (“Electric Guitar Tournament”—a highly-rated audience-participation guitar show…something of a Ventures-inspired proto-American Idol for guitar players—guitars were HUGE in the 60’s in Japan).

Vintage 1960's Guyatone GA-530A Guitar Amplifier

What’s under the hood? It’s a pretty simple and well-made amp. Three 12AU7’s (for preamp, tremolo and phase inverter duties), two EL84’s for output and a solid state rectifier and not much else. The speaker is labeled “Guyatone”, though I’m not sure if it was made by Guyatone or rebranded (there are no codes on it). Whatever its source, this is a sweet-sounding ALNICO speaker in the 20-watt range.

Vintage 1960's Guyatone GA-530A Guitar Amplifier

The sound of the amp is very cool and unique. Where most of the Univoxs I’ve heard are little blues and garage-rock machines, this amp is all about chime and cleans. Part of this, of course, comes from the low-gain 12AU7’s. A 12AX7 has, for instance, an amplification factor of 100. The 12AU7’s have an amplification factor of 17. The amp is voiced for cleans and isn’t (as you might guess from the tube line up) the loudest dual EL84 amp you’ll ever hear. Without mods, you can heat things up a bit with a 12AT7 in the preamp, but anything much higher than that makes it start oscillating and wailing a bit. Without some mods, it’s not going to be a high (or even mid) gain amp.

Vintage 1960's Guyatone GA-530A Guitar Amplifier

However, played clean (which it stays until about 7 on the volume knob), this thing really shines and sparkles. Byrds and Beatle type tunes sound incredible and it takes to a 12-string really well. Chords are articulate and well-voiced and the amp rings like a bell. Pushed into overdrive (from 7-10 on the volume), and the amp retains its trebly voice, but pushes the EL84’s into a Vox-like chime and grind (albeit at a lower overall volume than, say, an AC15).

And, while this combo may lack reverb for true surf tones, it’s got the awesome gritty sparkle to base your surf tone on, along with an absolutely KILLER tremolo. With tremendous range of depth and speed, it’s a very musical tremolo effect. One of the best I’ve heard in ANY amp. Add a ‘verb pedal, and you’re catching a wave!

Vintage 1960's Guyatone GA-530A Guitar Amplifier

Issues? Well, you are going to have a few when you buy a mid 60’s amp for under two hundred bucks. First of all, unless you know how to do relatively simple work like cap jobs and basic trouble-shooting for bad resistors and so on, the trip to the tech could cost more than the amp is worth. So, it’s probably not a great deal unless you know some basic repair and maintenance.

AND, there is a design flaw on this amp. The tubes are not mounted separately on the chassis, as they should be, but, instead, they’re mounted on the printed circuit board. This is problematic for a few reasons—the main ones being that it’s not nearly as study or durable as the proper mounting on the chassis and that it’s much easier for microphonic issues to arise (whether from the tube or the circuit board and then amplified through the tube).

Vintage 1960's Guyatone GA-530A Guitar Amplifier

Also, it’s not nearly as easy to modify a printed circuit board amp as it is on a hand-stuffed circuit board or a point-to-point amp. And you might want to modify this model for a little more gain on the preamp, via a nice 12AX7, pushing the rest of the signal down the chain. Or add a bypass cap to fatten up the sound. Both of these are still easy mods—just not quite as easy as if it were a point-to-point amp with a lot of space to be noodling around in the chassis.

Still, you want perfect for under two hundred clams? These are great-sounding, great looking little tone machines. And while the build quality may not equal Fender or Marshall (or even Univox), they are still pretty easy to fix and modify, and you can’t beat a little 12” combo with two EL84’s jangling and grinding for this kind of price. The Guyatone GA-530A is worth checking out—if you can find one!

Vintage 1960’s Guyatone GA-530A Guitar Amplifier from MyRareGuitars.com

I recently saw a later model (Blue faced) Supro Corsica going on eBay and the seller claimed THIS was the Jimmy Page amp…he was positive…everyone had it wrong…if you wanted THE TONE this was the Page amp. It, naturally, got the “question/comments” section crackling with replies (including, yes, I admit it, one of mine…I just can’t help myself sometimes) asking where this guy got his information, how did he know, and so on. He also claimed the Bluefaced Supros were EXACTLY the same (minus cosmetics) as the earlier Gray Tolex-ed models, which just isn’t true (I’m hardly a Supro expert, but just easy simple research will show you they often changed the guts over the years).

The upshot? The amp, which looked to be in so-so condition, sold for $450 amidst a series of increasingly angry and defensive responses from the seller about what idiots the people who were writing him were….Along the way, there were wonderful stories and theories about Page’s amp (it was destroyed in a fire, yet somehow is at the R&R Hall of fame…some have seen photos that prove it’s a Thunderbolt; some that prove it’s not…I half expected someone to say they had a photo where the grill cloth had the outline of the Virgin Mary head-banging in it or something).

And Thunderbolts (the most common, and probably correctly, Page-associated model) these days are drawing anywhere from $800 to $1,200.

And you know what? Page or no Page, cheap (ten years ago) or not cheap (today), they’re TOTALLY worth it. They’re very well put together (if not as easy to service as a Fender – but then, what, except for a Fender Clone, is?), have plenty of volume for a gig, take pedals well, and sound awesome without a pedal at all. It doesn’t really matter what Page played on those albums (or if and when Hendrix used a Supro), because IF YOU use a Thunderbolt, you will sound REALLY GOOD. And isn’t that the point of all this tone chasing us sick, diseased, deranged gear-addicted people do?

And, despite the enormous (and goody for all of us, I say) amount of boutique amps companies, there really aren’t many Valco-ish boutique amps out there. In the early 90’s, everyone seemed to be building a Fender Tweed copy (with variations, of course). Then, it was Fender Blackfaces. Then, the current 18-watt craze.

1960s Harmony 525B Bass Guitar Amp

And it makes some sense. With Tweed Fenders going in the 3-5 Grand range, why not pick up a point-to-point (or hand stuffed circuit-board) copy of one of those great amps for two thousand? But no one could build and market a Supro Thunderbolt clone, with high grade parts, for any less than the $1,000 you’d pay for an original with a cap job and a tune up. So, while their price has gone up (lots) in recent years, they are still something of a vintage bargain, and they’re awesome amp.

But what if you can’t scrounge up $800-1000 for that tone, let alone a couple thousand? Enter the Harmony 420 and the Harmony 525 bass amps (made by Valco in the, respectively, mid and late 60’s). It’s much like a Supro Thunderbolt, with some minor differences, on a budget. On a super budget. They can be found, with some regularity, in the $200 range. Wow! Well-built 60’s tube tone for that kind of price?

The 420 (in the black paper covering with the silver grill cloth) and the 525 (racing stripe!) are the same amp on the inside. They run a ½ of a 12AX7 for the preamp (leaving ½ unused for you gain-adders and modifiers), another 12AX7 as the phase inverter, and two 6L6’s for the output (all the same as the Thunderbolt). The speaker is a 15″ ceramic Jensen (ditto- same as the Thunderbolt).

Where they differ from their Page-ian (Page-esque? Page-larian?)brethren? A solid state rectifier and a different tone control (the Harmonys have separate 500k Bass and Tremble controls, while the Supro has a single tone pot) that makes it a little more constipated sounding than the Bolt (this can be addressed).

I snagged the one in the photo (posed with a beat up, amazing Harmony H-72) for 100 bucks from some clown who refused to ship it. Local pickup is always nice…especially when it’s all they offer and you are the local one! Turned out it was a pawn shop about fifteen miles away. This was a great deal – the speaker needs a recone, or I’ll probably buy a Weber Alnico for it, as I’ll gig with it and tend to get new speakers for that. Some minor (very minor) modifications to the preamp for more gain, new filter caps, and this thing is a sustaining singing overdrive blues/rock amp.

Even if you have no interest in picking up a soldering iron, you can buy these for around two hundred bucks and invest very little at your tech’s and get a vintage Valco-made amp with boutique tone for under $400. You can’t beat that.

If you can afford it, though, get the Thunderbolt, too. That tube rectifier sings. And, you know, it was on every single song Jimmy Page ever cut. EVER! He never ever ever ever recorded without his Supro! And, just so you know (and capture THAT tone), he always put it 18 inches to his left and 17 inches behind him, wore a paisley shirt whenever he played it and never ate hamburger the day of the recording.

And before that, Arthur pulled a sword out of this most legendary of amps and became king of England……and after that, the Supro Thunderbolt discovered America while looking for spice routes to Asia…and after that it wrote the Canterbury Tales. Or maybe I’m thinking of Communication Breakdown?

Sano Amplifiers

I’m going to start with the Ampeg, go Ken Fischer one up in sleepers, and save the amazing 415 for a later column (I was recently lucky enough to trade for a beat up 415, and it is truly THE sleeper 18-watt amp out on the vintage market… more in the next couple of months on that one).

To the Reverberocket. Along with having one of the coolest names ever (don’t ya love all the late 50’s and early to mid-60’s Space-Race names? Harmony’s Rockets, Ampeg Jets…the Atom symbol on everything from Gibson amps to Stratatone headstocks to breakfast cereal…remember Quisp, anyone?), it is a great amplifier. The early (1963 and some 1964) models used the nice and gritty 6V6 tube for output. This, according to legend, had them breaking up considerable quicker than the largely Jazz-centered Ampeg crowd (an image fostered by founder and, in 1964 still head honcho, Everitt Hull) wanted, and the design quickly shifted to the one most listeners are familiar with (with the clean fat-bottomed 7591 output tubes). Most had a single 12″ speaker with the early ones sporting big octal preamp tubes, and the later ones the more commonly scene (today, at any rate) 12ax7’s and the like.

Sano Amplifiers

I first heard one of these at an NRBQ show in the early 80’s and was hooked. Reverberockets have a reputation for being clean amps, and that’s true enough (though they can break up nicely when pushed). They do have a great clean (and crunchy) tone. But what, perhaps, doesn’t get enough play is their reverb. It sounds to me (ears being subjective, after all) to be a much deeper and more lush verb than the Fenders of the time. Jazzier and less surf-y (though Reverberockets may be THE most underrated surf amp ever) than the traditional Fender surf sound. Also, for your early Dick Dale tremolo rolling tone, Reverbrockets have it wired.

They are awesome amps. And you’re still able to catch one for under 500 bucks on the Ebay market (sometimes in the $250.00-300.00 range, depending on physical condition).

BUT, if you’re really in love with the Ampeg sound and want to stand apart from the crowd (or, err, stand apart from the dinky cluster who is standing apart from the crowd), you, my friend, want a SANO twin twelve. Check out the photos.

These are not, as some websites (and Ebay listings) made by people who worked at Ampeg, but a separate and consecutively running company right down the road (both located in New Jersey at the time). They might have been reading each other’s mail (or amp designs), though, because this SANO is a LOT like a Reverberocket with an extra speaker in the cab.

The Sano is a great and affordable way to get that super Ampeg Reverberocket tone at about 60% of the price (mine cost $300 and, as I said, has 2 twelves to the Ampeg’s one). This is a twin 12″ amp (around 30 watts) with Oxford Alnico speakers. The AMAZING reverb (same sound and circuit as the Ampeg talked about earlier). Good, if not incredible tremolo, topped off by a SUPER cool swirly grill.

Sano Amplifiers

And, yes, icing on the cake, it has the 60’s spaceman swirly atom graphic on the control panel. YES!

The guts? 3 12axy’s for the preamps and reverb with a 6sc7, for the tremolo. And two 7591’s for clean, bottom-rich output…an incredibly clean full sounding amp that when cranked, can garage rock with the best of them. Not so loud, but plenty for mid sized and below gigs. It has two channels, which you can bridge with the convenient, though mis-labeled “stereo” input.

If you see them on Ebay, you should be able to snatch a minty one for under $350. A great deal for a vintage amplifier built like a tank. And now that there are new 7591’s on the market, there’s really no good reason (as there was ten years ago) to avoid Ampegs and Sanos that use these underrated output tubes, or to switch their circuitry to accommodate 6L6 tubes.

Be aware, though, there are a lot of Sano amp models. (For info on some other Sano amplifiers, and a history of the company, check out singer-songwriter Larry John McNally’s website: http://larryjohnmcnally.com/sano_amps.html) Some have a duel EL84 output and a single 12″ speaker (never heard it, but would like to), and SEVERAL that look a lot like this model are solid state. Ask questions, as always, before you buy. There are also models with a single 15″ and two 8″ speakers (for the accordion amplifier market…which has, well, dwindled since the mid 60’s).

So there you have it. Two sleepers in one (three, if you count the early 6V6 output Reverberockets). Surf is, indeed, up. New Jersey surf, that is.

Sano Amplifiers (Like the Ampeg Reverberocket Amp) from MyRareGuitars.com

So, I was looking for a single-ended amp. Say what you will about class A/B amps (and, to be fair, most of the great recorded tones in rock history are class A/B push-pull amps), some of them don’t really get singing until they’re too loud for the bedroom or studio. Sometimes you just need to hear that cranked tone without getting the knock from the neighbors. To quickly recap:

1. I wanted a small, easy to carry amp that screamed at relatively low volumes.
2. I didn’t want to spend much money (I’m a cheap bastard…part of me thinks I could never truly love a 59 Bassman unless I scored it at a yard sale for a hundred bucks. Now, tone matters more than money to me, but I tend to love the tone of crappy amps just as much as high enders, so I’d feel like a stooge dropping that kind of money on an amp. Especially since I play them and would ruin the collectable value of anything by gigging with it).
3. It needs to be an amp that another guitar player would say, “What the fuck is that?

1940s Fidelity Amplifier

So what did I buy? A late 1940’s FIDELITY, of course. Haven’t heard of FIDELITY? Me, neither. But it met the needs. It was very light an easy to carry. As for meeting my volume needs…it was VERY quiet. Dead quiet. As in, silent. So, that part needed some work. Sixty bucks. Not bad. Less than an assembly-line stomp box. It looked like a 50’s space heater in crap brown with tootsie roll brown and vanilla cream paint and chicken head knobs. Score, Daddio

When it showed up, my wife shook her head. This can be a good sign or a bad sign…it depends on how it turns out down the road. Sometimes, I fix these things up and make lots of money and buy her a new bass. Sometimes, I lose money and crap piles up in the garage. I try to remind her often of the former and play down the latter as much as possible.

1940s Fidelity Amplifier

Anyway, this little beast didn’t need much work. This is one of the pleasures of working on a Champ-style practice amp. They have so little in them, there’s simply not much to go wrong or fix. This one, it turned out, only needed a filter cap job, a new preamp tube and one coupling cap. Piece o’ cake. Twenty minutes of soldering and one $4.00 7F7 tube later, I had a monster little Champ-esque amplifier (actually it sounds a little more like the Gibson Skylark than a Champ, but that’s cool by me) for under $80.

1940s Fidelity Amplifier

Quirks? Some. The old Rola was kind of tired, so I saved it and put in a new Jensen Mod I had laying around (not a bad little speaker, but not a vintage Jensen, either…expect a future upgrade). The 7F7’s are supposed to be very loud and micro-phonic (which was why we don’t tend to see them in guitar amps after the mid-late 40’s), but this one sounds just fine. And they’re cheap, so it’s not like you’re hunting down good EL86’s or anything. Also, one thing that took some getting used to was the tone knob is backwards by contemporary standards. That is, turn the creamy chickenhead to the left, you get more treble (and more drive and volume). Turn to the right, and it gets very bassy and like a chewy jazzy tone.

The other cool thing about these old non-collectable brands? A modification isn’t sacrilege. I added a “speaker out” jack to drive a bigger cab (using a practice amp cranked through 4X12’s is too much fun…a little amp can move a lot of air in a big cab) and a “line out” jack to use this as a pre-amp with a bigger power amplifier at shows.

1940s Fidelity Amplifier

Where can you find one? My guess is that FIDELITY was a housebrand (like Holiday or Silvertone), and these might be Valcos or some other maker. But I have since seen 2 or 3 of them on Ebay, not going for too much money. Also, there are several other brands (and no-brands) that look much like these, so keep your eyes peeled, don’t pay too much, and score a little gem that will have other guitar players saying “what the hell is that” and have your significant other shaking his or her head when the UPS/Fedex people come knocking.
