You rip into the first bend, and *SNAP* – your heart sinks as your once-tight B string is now a wet noodle flopping around between your fingers. You stumble through the rest of the song, frantically improvising parts that don’t require the use of that string, and when it’s all over you think to yourself “Well, I guess it’s time to put a new string on now.”

The phrase “if it ain’t broke, don’t fix it” simply does not apply to guitar strings. The notion that you should only change a string if it breaks is completely backwards; even if you’re not planning on playing for thousands of screaming fans any time soon. The reality of guitar strings is that regardless of how fresh or old they are, there is always a chance that they can break. Whether you’re a seasoned pro with a guitar tech changing your strings every night, or a basement player with strings that haven’t been changed in months, a break can happen. With regular re-strings and proper instrument maintenance, however, it is far less likely that a break will occur, and you’ll be more likely to make it through a song with all six strings intact.

Why?

Strings can break for many reasons, and one of the biggest culprits for breakage is corrosion. Dead skin, sweat, and dirt build up on the strings over time, causing their metals to break down. The longer you leave the string on, the less stable it is going to become and make it more likely to break. Even if you aren’t regularly playing the instrument, the moisture content in the air will have a similar effect on the strings – it just might take a little longer than if you were playing it.

That said, you can’t always blame the string when one breaks. If you’re consistently having issues with strings breaking, it might be a good idea to take a look at the bridge saddles, nut slots, or machine heads. Something could be sharp, or perhaps catching the string in a way it shouldn’t be.

Alright, enough about breaking strings! Preventing a string break is not the only reason for a change. In fact, it’s more of a byproduct of the real reasons.

Just as corrosion can lead to an eventual break, it also causes the string to not function to its full potential. A string covered in grime won’t resonate properly, and will sound dull and lifeless. On top of that, an older string has been under a lot of tension for a longer period of time. This means that it has been stretched more, which can result in more difficulty staying in tune. Changing your strings before they get to the point where they are coated in grime, corroded, or stretched to oblivion will keep them sounding fresh, lustrous, in tune, as well as help prevent them from breaking mid-song.

So then, the question becomes how do you know when a string is passed its expiry and it is time to change it?

For the more experienced player, it turns into a preference thing. Some players like the snappy sound of a brand new string, while others prefer the sound of strings that have been “broken in” a bit; maybe a couple days’ or even a week’s worth of play on them. Obviously not everyone has the luxury of being able to change strings every few days, so as a general rule of thumb I’d recommend aiming for a time period between two weeks and one month. Before you’re able to decide what it is you really like, there are a few things you can consider.

1. Look and feel

If your strings are looking dull, or even black – and feel rough or sticky, it’s probably time to swap them out.

2. Sound and tuning

If your strings don’t sound as clear or present as you remember, and you’re having difficulty keeping your guitar in tune, you may want to change your strings.

3. Playing live or recording soon?

If you’ve got a date set, and can’t remember when you changed your strings last, then it’s a safe bet to change them up. Make sure you swap them out at least a few hours before you plan on hitting the stage though – brand new strings have a tendency of falling out of tune as they aren’t yet used to being brought to tension.

4. Budget

Of course, everything costs money. The best thing you can do is learn to properly re-string by yourself, and use a quality brand string. Make sure you use the same gauge strings as you had on your guitar previously, as changing sizes may throw your guitar’s neck out of whack… meaning you’ll need to spend more time or money to get it set-it up right!

That’s it, in a nutshell! As long as you keep these things in mind, you should be able to maintain a great sounding and feeling instrument that will really make you want to pick it up and play!

When Should I Change my Guitar Strings? from MyRareGuitars.com

At some point in your guitar-playing life, you’ll likely experience a faulty tuning key and need to replace it. Maybe your current tuners aren’t accurate enough, or seem to weigh your headstock down? Or maybe you just like the look of Kluson “green keys” instead of your Gotoh’s. Whatever the reason, it’s important to have at least somewhat of an understanding of what these things are and how they work before you spend money to replace them.

The first thing you’ll need to look at, of course, are the technical specs of the tuners you currently have to make sure you don’t cause yourself too much grief installing the next ones. The best case scenario would be you finding a set that will slip seamlessly into the peg-holes of your guitar without any modification. The next best would be the required installation of “adapter bushings”, which are basically just different thicknesses of metal used to, well, adapt to variations in diameter.

The last thing you want to end up doing is widen the peg holes. Sure, it might work – but if you’re doing this to a valuable guitar, you don’t want to be doing anything that is changing it from its original condition.
Most machine heads will show in-depth measurements of all of their components so there are no surprises when it comes time to install. A good example would be here on Stewmac’s site that shows basically everything you’d need to know as far as sizing goes.

Aside from the physical-size measurements of the peg, one of the first specs you’ll always see is a ratio such as “14:1”. This has nothing to do with the installation of the part, but rather its functionality. Now, let’s not forget the ultimate reason these things exist… to keep your guitar in tune! If you were having trouble tuning, or your tuner seemed to constantly “skip” over notes or pitches, this ratio is something you want to pay close attention to. Essentially, the higher the number, the finer the tuning you are able to do. The first number is the number of full turns it takes you to turn the peg before the inner gear completes one full cycle. Therefore, if you had something that was 1:1, you can imagine how hard it would be to zero in on any given pitch. If you feel like you want something that’s a little more precise, try to find a higher ratio tuning key. I’d recommend something 16:1 or higher.

A further method of helping keep your guitar in tune would be to invest in a set of locking tuners. They basically do what the name suggests – lock your strings in place. They help prevent string slippage without the string having to be wrapped around the peg-shaft “X” number of times, which makes for an easier re-string. At the end of the day, a string is going to go out of tune because something moved somewhere. Locking things in place is a good way of preventing that!
If you’ve ever held a really old guitar in your hands and tried to tune it, you may have seen plastic tuning pegs literally fall apart in your hands. Over time, and from lots of use, the plastic can come loose from the metal. At first this can cause tuning problems as it doesn’t properly grasp the mechanism when you turn it, and later, the piece can crumble and break. You can find high-quality keys made with plastic that will last longer than others, but if you really want something that will stand the test of time, metal is your best bet.

The last thing you might want to ask yourself when considering a new set of pegs is “will this change affect my tone?” You’ll get a different answer for this depending on who you ask.
First of all, of course a better set of pegs will be less prone to rattle, fall out of tune or break which are all things that I think we can all agree makes your guitar sound better. The only other thing that can really be argued for having an affect on your tone here would be the weight of the pegs. Different players and luthiers could argue for days over which is better – a heavier headstock or lighter. Some would say the heaviness would take away from the vibration of the neck, while others would say it adds sustain. Some would argue that it really doesn’t matter. One thing that we can be sure of, however, is that a heavier/lighter set of pegs might change how you play. A guitar that is heavier or lighter at the headstock will have a different balance, and will feel different in your hands and around your shoulders. Probably not by much, but it doesn’t take much for a guitar to feel different, and consequently make you play different. My advice would be to go with a set that doesn’t change the balance of your guitar too much.
Remember, the majority of your tone comes from your fingertips, which comes from you, which comes from your current state of mind, which can be affected by how comfortable or uncomfortable an instrument is in your hands!

Tips on Tones: Issue #21 – Machine Heads from MyRareGuitars.com

Joey Leone’s recent article on the importance of set-up was spot on. Years back, I worked as a salesman in a small, independent music store. I’d never worked in music sales before, so unpacking brand new guitars fresh off the UPS truck was a new experience for me. I quickly discovered that they were almost never properly adjusted. It was a roll of the dice at best. The guitars that happened to come in playing well were the first to go out the door in the hands of happy, paying customers. The other instruments would hang on the wall a lot longer, while we repeatedly explained that a professional set-up would make them play and feel much better. So I got to thinking that if I learned the basics, and at least got the guitars and bass guitars into reasonably good adjustment, sales would go up. I started talking to our guitar tech, and asked him to explain to me how it all worked. He was amazingly patient with me while I relentlessly picked his brains, until finally, I began to “get it.” I got pretty good at setting up the instruments, and sales went up substantially—not that the owner of the store was in a hurry to give me a raise for my efforts!

Still, I was glad for what I’d learned. While major repairs and maintenance (including fret work and the neck set on acoustic guitars) were things I was wise enough not to tackle, routine adjustments became, well, routine. The electrics were the easiest to work with, because most of the adjustments were done mechanically, with a screwdriver and an Allen wrench.

I found a quick way to scope out a truss rod adjustment, without needing the expensive machined straight edge our tech used. Using both hands, I’d just press the bass string down in two places on the fingerboard, simultaneously–say at the third and 11th frets–and then pluck the string with a free finger. If the string bottomed out, it meant the rod was too tight, and the neck too flat. Conversely, if I could see much more than the thickness of a playing card’s worth of space between the string and the frets (looking from the side, as you would while playing), it meant the rod was too loose, and the neck had too much forward bow.

After that, I’d start adjusting the saddles—up or down for string height, and on the electrics, forward or back for string length. These two adjustments—height and length—are highly interactive. If your strings are higher, you have to press them down farther to play a note. That means more stretch, higher tension, and raised pitch—resulting in the need for lengthening the string, by moving the saddle away from the nut a bit. Lower strings mean less stretch, and less need for compensation. Different players like different string heights, of course, so there’s no single right way to do this, but at the store, I’d try to find a middle ground that would satisfy most players.

Nut slot adjustments are something untrained players shouldn’t mess with. The tech showed me how to do them, using an X-acto saw blade and 400 grit sandpaper. If the slots aren’t shaped properly, the strings won’t seat and flex properly, causing all sorts of problems. I started out doing nuts on cheap, entry-level guitars that had action bad enough that I could hardly have made them worse. And amazingly enough, I had a pretty good touch, and was able to do them well. Still, I left the top-of-the line instruments to our tech, though I’ve done the nut slots on my own pro guitars, since then. Ironically, most guitar techs don’t take the slots down far enough, in my opinion. That’s because if they go too far, the strings start buzzing, and they have to make you a new nut, or at least do some extra shimming—things they really don’t want to take the time do. I think the open string clearance between the nut and the first fret should be about the same as the clearance obtained between a closed string (that you’ve pressed down at a given fret) and the next fret up (toward the bridge). That way, you don’t get additional stretch at the first fret, sparing you the all-too-common aggravation of a guitar that plays sharp at the first fret. But talk to your guitar tech about it. As the saying goes, don’t try this at home.

Worn frets make guitars play sharp! That’s because as a fret wears down, the string vibrates from the front edge of the fret, rather than from the crown—effectively shortening the string, and thus slightly raising the pitch. Worn frets can also cause string buzz against higher, less worn frets. If you then raise the action to offset this, you create all sorts of tuning and playability problems. So get your frets worked on, when they need it. A guitar tech I know suggested that changing your strings is like buying gasoline for your car—something routine and inexpensive. Getting your frets adjusted and replaced is like buying tires. More expensive and done less often, but it’s something you simply must do, from time to time.

Keeping your guitar in tune requires strings that still have some elasticity. They don’t have to be brand new, but over time, strings become stiff and brittle, long before they break. Stiff, brittle strings play sharp, so once they reach that point, it’s time for a new set.

String gauges can make a difference, too. I like fairly heavy strings on my Strat. I use a 12 to 52 set, with a wound 3rd string—pretty much the same gauges I use on my acoustic flat top. I find them more stable, tuning wise, than lighter strings, and I like the fatter tone I get. But some people have no trouble with the lighter, faster, 9’s, 10’s, or 11’s. It just depends on your touch and style.

The weather affects your guitar! Humidity swells wood, higher temperatures expand everything, colder temps contract everything, and all of these variations affect the tension on your strings. A guitar can be in tune at home, and get wonky in a cold car trunk on the way to a gig. At the gig, you re-tune the still-cold guitar, only to have it shift on you again as it warms up in your hands, requiring you to re-tune again (and again!). Don’t worry. It’ll eventually settle down. Better still, arrive a little early, and let the guitar warm up before you play it.

Finally, let me just touch on the question of scale tempering. Musical scales are built around theoretical mathematical ideals, but real world instruments have built-in compromises. These compromises are called scale tempering. The modern equal-tempered tuning system was a major innovation developed for keyboard instruments during the time of J. S. Bach, and his composition, The Well Tempered Clavier, demonstrated its effectiveness. Prior to that system’s introduction, you could not play in some keys without retuning your keyboard. These days, most guitars are built according to the equal-tempered system, but ironically, acoustic pianos employ a variation called “stretch tuning,” to compensate for the sharp harmonics generated by their stiff, massive, bass strings. The piano sounds more in tune with itself, but it’s a challenge to get guitars and other instruments in tune with the piano. Guitars with compensated nuts, guitars employing the Buzz Feiton nut and tuning system, and guitars with computer-designed curved frets are all examples of recent attempts to improve tuning accuracy and compatibility with keyboards.

There’s no way this short article can address all of the things that affect how in-tune a guitar plays on its own, and with other instruments. But I hope it points you in the right direction.
