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.

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.

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.

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.

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.

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.

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.

Now the next question you may ask is, “are there any guitars that will cut through coming from one of these Tweed amps?” I say yes, plug a Strat in that same Pro and see how awesome it sounds, thick yet trebly.

So the point of this column is, the choice of guitars is a primary decision – I don’t think there are many players out there saying “I wanna play a Twin Reverb what guitar should I get?” – and the amplifier choice is key in getting the sound you want. I am sure that there are some guitar strummers out there who would embrace the potential “mismatch” in guitar and amp symmetry, to assist in them finding there own voice. To this I say Cheerio! Always seek your own sound. Sometimes I believe that playing a Tele through a Twin Reverb can be a potentially intimidating experience as so many great guitar players have that combo as part of their signature sound.

So here are a few suggestions that seem to work for me.

Fender Vibrolux Amp (Blackface)

#1: Fender Blackface Vibrolux amp and most Gibson equipped guitars especially a Les Paul, an SG, or any ES series guitar.

This is a great combo for rock, blues, country, pop and even jazz at a low volume. This was originally brought to my attention by my friend and fellow Vermonter John Sprung (knower of all Fender amplifier lore, etc). And as always he was right, this combo sound great!

#2: Fender Brownface tremolo-equipped amp and a Stratocaster. This is a sound from the gods, an incredibly thick, full, hypnotic sound, not too dissimilar to Jimi’s sound using the Uni-Vibe but, I feel a more organic sound than even that striking sound. I do believe that when you start to overdrive this set-up from the front end with a pedal you do lose some of the clarity and basic integrity of this sound. If you don’t have a Brownface Fender and don’t want to change your primary amp you are now using just to get this sound, you might want to check out the Victoria Tremverb, it’s a tweed free standing unit ala the Fender Reverb unit but has the Brownface tremolo circuit also.

1974 Marshall 18-watt combo amp

#3: Marshall 18-watt combo amp and a Les Paul. Not much else to say here really, this sound will absolutely blow you away, it’s the sound we all marveled at on those early Clapton/ Peter Green recordings. I know a lot of you are saying that’s the “Bluesbreaker” sound and yes you are right it is but, I believe you can only get that sound from a hand-wired Bluesbreaker combo.

The new Reissue Marshall 1974x HW is the absolute balls! I own three of these and cannot tell you how happy I am with them. Get one!

Fender Twin Reverb Amp (Blackface)

#4: Fender Blackface Twin Reverb amp and a Fender Telecaster. Clean, toppy and true, baby. Your technique will show through with this set-up like no other. If you are confident and want to be heard this is true test. And please don’t fool yourself into thinking that this is a country exclusive combination, because it is not, ask Mike Bloomfield. Those of you familiar with his guitar lineage will know that before the great Bloomfield went to the “Burst” he played a Tele through a Twin for years. Again I will tell you that this set-up will work for blues, rock, country and yes, even jazz.

If you are looking for this sound in a more manageable context try the “Baby Twin” the BF Pro Reverb instead. It will sound similar but break up a bit easier, and a bit more “club owner friendly.”

Vox AC-30 Guitar Amp

#5: Vox AC-30 amp and the Rickenbacker 12-string and the Gretsch Chet Atkins Models. Yeah I know another no-brainer, but how could I speak on the guitar-amp relationship without discussing the perfect one. As a foolish young man I was heard to say on occasion “imagine if the Beatles had used Fender amps and Gibson guitars instead of those god awful sounding Gretsch’s.” Oh boy was that a moment of genius, heh?

The AC-30 and its Top Boost circuit helped the Gretsch cut through so well on those recordings while still remaining full and complete sounding across the frequency range of the guitar (a reoccurring theme in this column I’d say).

Now onto the Rick 12 and the ¾ scale 325 model that John Lennon favored in the early Beatle days. Both of these guitars were equipped with what has been called the “toaster pickups”, These pickups did not have a lot of output which only enhanced the “jangly” sound we all came to love back then. The AC-30 embraced this aspect and produced a clean but yet again strong sound with not much in the bass end but with plenty of treble and mids. Another seldom ignored aspect of this sound was the fact that the Ricks came with flatwound strings and were smart enough to supply the Lads with replacements.

Just a couple of quickies for you.

• Polytone Mini-Brute and a Gibson ES 175 (Joe Pass sound, but you can’t buy his technique, sorry!)
• Magnatone tremolo amp with a Stratocaster (if it’s good enough for Buddy Holly its good enough for me)
• Any cheapo hand wired amp from the early 60’s (Valco, Supro, Kalamazoo, take your pick) with a Danelectro lipstick pickup outfitted solid body guitar.
• And last but not least, a Tweed Fender Champ and any quality solid body guitar, cranked up to 10 baby!!!!

Feel free to email me some of your faves and I will include thrm in future columns.
