So you have a new bass – or, an old one that you found at a pawn shop, from someone you contacted through Craigslist, or one that you inherited from your older sibling. Maybe it’s in good condition, but it’s been sitting under your bed for a while. It’s either the prettiest thing you’ve ever seen, or well-worn and beat up with plenty of belt buckle rash. No matter what state your new (old) bass is in cosmetically, you have to keep it up to playing standard, and surprisingly, you don’t have to spend a ridiculous amount of money. But first:
How often do you play it?
Some aspects of instrument maintenance depend on how often you play it, and where you play it. For example, if you gig regularly, then maintenance is a weekly, maybe even daily thing. If you use it mostly for practice at home, then it’s a little less often. If you use it once in a blue moon… then you obviously won’t maintain it as much, but you have to ask yourself if you really need it at that point. All of that said, regular maintenance simply means that it’s proportional to the amount of use you get out of your guitar; you don’t need to be changing strings every day when you only play it once a month.
The subtle things add up
Most aspects of maintenance are minor, but like a car, they can quickly add up and make playing your instrument unnecessarily difficult. The good thing is that you don’t have to be a luthier to correct these small problems, but you DO have to be familiar with how your guitar is put together, because not every bass is the same. For example: the truss rod (the metal rod inside the neck that keeps it stiff) is accessed from the body on my #1 bass; the same component is accessed from the headstock on #2. Get familiar with the small things such as that, as well as the bridge’s construction – which, again, varies from guitar to guitar. So, then… what are these subtle things?
Piece by piece

The bridge, made up of the saddles, sits opposite to the headstock where the tuning posts are. As mentioned above, you can’t see it, but the truss rod is inside the neck, and that keeps it from warping. On one end of the neck, you’ll see the nut, where the strings sit; this is, on most guitars, the zero fret (the rest of the frets are the steel markings where you press down the strings on the neck, all located on the fretboard).
The Adjustment Bureau
So what adjustments can you do? For starters, if your strings tend to go out of tune quickly, you may need to tighten your tuning posts, re-align them, or get them replaced completely. A typical set of posts goes for about $25-$30. Although a little harder (and requiring more patience), you can lightly file down the nut slots if the strings are sitting too high. (Probably best to leave it to a professional, but you can learn how to do it yourself.)
Another indication of strings going out of tune is improper intonation. The science behind fretting a string is that you’re essentially cutting the length of the string between the nut and the bridge, so when it comes to intonation, the shortened length has to be just right. How do you discover this? First, tune the string to pitch as close as you can using an electronic tuner (chromatic works best), and then play it open. Now, play a harmonic by lightly touching the string at the 12th fret (marked by a double dot on the fretboard in many cases) and plucking the string, letting your finger go as you do. If the two notes – open and harmonic) are significantly different, then the intonation is suspect. This is fixed at the bridge saddles, and using a small screwdriver, you can move the saddles back or forward. The general rule is that if the harmonic is flat, you need to move the saddle forward.
The neck can warp inward or outward, and it can twist as well. No matter which way it’s warped or twisted, the truss rod can get it back to normal. Now, this is a bit tricky, but when adjusting the truss rod – which is done by using an allen wrench (a hexagonal-shaped screw driver for those not familiar with tools), you can’t turn it too quickly. Now, I emphasize the CAN’T. You can seriously screw up your neck’s orientation with this adjustment, so make sure that a) you know which way to turn the truss rod, and b) consult a professional if you can’t seem to get it right. In fact, if you really feel like doing if yourself, it’s probably best to seek thorough advice first.
Action – the height of the strings on the fret board – is also something to keep an eye out for. Action might need to be adjusted if it takes more force to press down the strings, or if you hear fret buzz when holding a note (or even playing it open; the string vibrates and hits the fret). Again, at the bridge, the entire assembly is usually held up by two screws on either end, with one being higher than the other. This is done on purpose, so that the strings match the curvature of the fretboard. You can move the screws up or down, but remember to keep the high/low orientation similar. A good indication of action is sliding a credit/debit card underneath the strings at the 3rd fret. If the raised numbers are hindering the card from coming out, then the action may be too low.
Other stuff that isn’t easily fixed
Problems with your guitar’s electronics (wiring, pickups, volume/tone pots, switches) aren’t as easy to repair, so those are best left to a pro. But be aware of things that may hinder your sound such as scratchy pots (crackling whenever you adjust volume or tone), bad wiring, faulty pickups and switches, and loose input jack assemblies. I’ve had problems with bad wiring and bad input jacks – in the middle of a gig – and they aren’t too pleasant to deal with. So before a gig, check your connections. If you can nip an electrical problem in the bud by getting it fixed before a gig, you’ll save yourself a lot of headache. And you’ll sound great, too.
Conclusion: looks can be deceiving
It doesn’t matter what kind of bass you have; if it’s unplayable, it’s as good as a piece of firewood. Whether you have an Ibanez, a Fender, a Peavey, or a high-end piece of artwork that’s one of a kind, you need to learn to keep it in good playing condition. There are plenty of resources on the Internet as well as in music stores about caring for your bass, and they’re much more in-depth than what I’ve talked about here. But as I’ve mentioned above, if you’re unsure about adjustments (even after doing proper research) do yourself a favour and consult a professional, and have them do the work. It’ll cost less than having to buy a new guitar. My hope with this article is to inspire you to at least be aware about the things that may need to be dealt with as you learn bass.
