Pro Tips for DIY Guitar Work

Learn some simple tricks to improve your DIY guitar maintenance and repair work. Learn how to do better work and minimize the chance of common preventable problems.

Learn How to Take Care of Your Gear

If you have anything of value you need to understand how to take care of it. This is certainly true when it comes to your acoustic or electric guitar or bass. Even if you rely on a luthier or guitar tech to do service work, you can still help with the care of your gear.

1. Handle Your Guitar With Care

Almost every dent, scratch and abrasion could have been prevented. Most of this damage occurs from a momentary lapse of judgment. From banging your guitar into something, placing it where it was able to fall, or failing to use a protective case most damage is avoidable.

Don’t eat or drink near around your guitar. One spilled drink can cause electrical problems, cause screws or hardware to rust, and sometimes damage wood finishes.

Protect it other people. Some roommates, kids, and guests can’t keep their hands off of your guitar. If you’re working on it and need to stop, either put it away or ask them to not handle it. Personally, we advise you to never trust cats. They’ll jump on your guitar and just look at you.

2. Protect Surfaces While Doing Work

When it comes to working on your guitar, always place it on a padded, soft surface. Minimize reaching over the guitar for tools and other items you could drop on it.

Tape is cheap and t-shirts are super handy. In many situations, you should take a few minutes to tape-off or otherwise cover non-work areas. This is especially true if you are soldering over or near your guitar. Taping off your fretboard to polish frets is a non-brainer.

3. Love Your Screws

When you’re replacing screws, keep in mind that they’re not holding down the main guns on a battleship. Tighten them enough to be snug but do not crank them down as tight as you can.

Before you install a screw, swipe the threads through a little candle wax. It lubricates the threads and gives it a tiny bit of corrosion protection. You’ll find it’s then much easier to remove them later. You may be interested in a forum discussion on what kind of lubrication to use on guitar screws, where wax is the top suggestion among guitar players.1.

And note this, always use the appropriately sized screwdriver. Using the wrong size screwdriver is a quick way to strip out the head.

4. Periodically Check Fitness

From screws holding strap buttons, hardware and knobs to pickguards you should periodically make certain things are not coming loose. If not, you’ll almost certainly discover one day that a screw has gone missing.

5. Keep Cover Plates Installed

Believe it or not, the top guitar manufacturers actually know what they are doing – including putting cover plates on cavities. If it made a guitar sound better (and would lower manufacturing costs) they would leave them off. Forget what your friends say about “it looks cool” or “you can change strings faster” or “your tone will be awesome”. Cover plates are protective, Use them.

6. Clean Your Guitar

It’s easy enough to play your guitar, then just set it aside. Investing a little time to care for your guitar’s appearance will keep it looking great and also preserve its playability. In fact, the experts at Premier Guitar published an article with a lot of information on cleaning a guitar, including compelling reasons to do so. Author John LeVan stated, “Over time, sweat, dirt, and oils build up on the guitar’s finish and slowly break it down. This causes the finish to develop a hazy film and become discolored. In addition, if your sweat has a high acid content (low PH balance), it can actually cause the finish to deteriorate, especially where you rest your arm. Sweat contains water, acids, salt, and several minerals that are corrosive to finishes and hardware. When you add in environmental issues, such as dust and pollen, it’s no wonder our guitars get so filthy.”2

7. Use Hangers Instead of Racks

Using wall-mounted hangers is vastly superior to storing your guitars in racks. Over time, an instrument hanging vertically will not develop neck issues like one stored in a rack. Gravity, the distribution of weight, and effects of pressure are undeniable factors in shaping wood (good or bad).

More reasons for using wall-mounted hangers? The folks at Guitar Grip recently wrote an article that gave 5 reasons to mount your guitar with a guitar hanger. Specifically, they cited spatial design, motivation, convenience, out of reach, and safely preserved.3

When upgrading to wall-mounted hangers, we highly recommend the style of guitar hangers with locking tabs. This is your best assurance of preventing a catastrophic fall. It’s worth mentioning that you need to be careful when using these from Thinline necks that may fall through the hanger. When you install the hanger it’s a good idea to make certain at least one of the screws goes through the drywall and into a wall stud.

8. Keep An Eye on Humidity

Wood is highly responsive to the amount of moisture dissolved in the air. This is especially true with acoustic guitars. Ideally, you can keep your guitar in a climate-controlled environment where relative humidity stays around 45-55%. To keep an eye on this you can go to Amazon or eBay and pick up a Hygrometer for around $15. The pros at wrote an article that says, “Humidifying your guitar is an important part of maintaining your instrument. So to protect your precious instrument from damage, you’re going to want to find the best guitar humidifier for your situation.”4

If you keep your guitar in a reasonable level of humidity and stable temperatures you’ll find playability (tuning, etc.) is easier to manage. Extreme dryness or humidity levels can actually ruin an acoustic guitar. See our article on How to Prevent Guitar Humidity Problems.

9. Keep an Eye on Temperature

Temperature is another out-of-mind factor in guitar maintenance. In addition to humidity, wood is also very sensitive to temperature changes. If you ever heard an old house creak or pop at night its because the wood is adjusting to the temperature dropping. Although on a smaller scale, your guitar will do the same. Too much expansion and contraction can crack finishes and cause laminated joints to break. At the very least, the expansion and contraction will play havoc on your neck (meaning tuning and intonation). Try to keep your guitar in a relatively stable temperature range.

10. Change those strings!

Yeah, guitar strings cost money (especially if you’re a bass player!) and are not a glorious purchase. It’s easy to slowly get used to those old, corroded, dirty strings and not notice what it does to your playability. Dropping a few bucks on a good set of strings will make your guitar tone better and they will feel much better. If you don’t know how to change your guitar strings simply catch a few YouTube videos. You can learn how to change guitar strings in under 10 minutes.

If you really like your guitar, learn to take good care of it. Read available info but beware of advice from idiots on forums. Always get information from reliable sources, and put your knowledge to work.
