PG answers some basic questiosn you may have about tuning your guitar!
How do you tune a guitar?
Tuning a guitar is the process of adjusting the tension in a string to bring it to a specific note. In practical terms, that involves turning a tuning head on your guitar’s headstock to tighten or loosen the string that’s wrapped around a corresponding peg.
What tools do I need to tune my guitar?
Just one: a tuner. If you have an electric guitar, you can buy a tuning pedal to plug your guitar into or you can buy a clip-on tuner, which clamps onto the headstock and works with any kind of guitar. You can also use free tuning apps and websites.
What does flat and sharp mean?
Flat means that the note is lower or deeper than what it should be. Sharp means that it’s higher than it should be. In both cases, it means you’re out of tune or your strings aren’t tuned to the notes that they need to be.
What notes do you tune your guitar to?
Standard E tuning is the most popular guitar tuning, and it goes like this, from top to bottom of the fretboard: E-A-D-G-B-E. My first guitar teacher taught me a little memory trick for remembering: “Eat at Denny’s good breakfast everytime.” Thanks, teach!
Are there other tunings?
Yes! There are nearly endless tunings for guitar, and some are easier to play then others. For example, popular open tunings like DADGAD make it fairly easy to produce pleasant, rich sounding chords with very simple finger positions. Drop D tuning, which simply involves dropping the low E string in standard tuning to a D, is another wickedly fun and simple tuning used by hard rock and metal guitarists.
Can’t guitars tune themselves nowadays?
Some modern guitars come equipped with self-tuning machines on the headstock, and automatic tuning machines like this one are hitting shelves, but they’re still rare to see and often have questionable accuracy. Best to do it yourself for convenience, accuracy, and ear training.
Having problems keeping your bass in tune? Before you swap out the tuning machines, ponder a few facts.

Have you ever wondered why some of your instruments go out of tune faster than others, even though you can’t identify a specific reason why? Tuning instability is a much bigger problem for guitarists than bassists, yet because modern bass players are often asked to do more than just keep the groove, tuning and intonation have become important issues for low-enders too. Playing an extended-range bass, doing solos, or even just covering a wider frequency spectrum requires you to stay in tune if you want to keep your gig. Naturally, many bassists who wrestle with this problem assume their tuners are the source of any instability and immediately swap the machine heads as a way to combat it. There are several things you can do to avoid tuning instability, but it’s rarely the tuner that’s causing the problem.
To get an idea of what could be the cause, it makes sense to look at the problem the other way around:
If you were to design the bass with the most stable tuning of all time, how would you begin? First, you’d get the shortest possible active string length. By active, I mean everything that is under tension. Remember, you can’t stretch what’s not there. The minimum would be the scale length plus all space needed for either tuning or intonation adjustment. The tuner could be a locking version, reducing the string-length on the axis, but even better yet would be a linear and non-winding tuner.
You’d also need to have two saddle points for each string and both should be very slippery to equal out any differences in tension along the string. A solid, stiff body won’t have much effect, but you might want to add some lacquer to save the body from moisture changes. Same thing for the neck, which is much weaker and these days is often combined with reinforcing layers of carbon. Lastly, you could eliminate all temperature- and moisture-sensitive material. Voilà —you’ve just designed your first headless bass in the classic Steinberger style!
Now, given that the majority of bass players tend to own Fender-style basses, it makes sense to look at the differences between those and our hypothetical design. We want to know how these differences potentially affect tuning stability. The most obvious difference is the headstock, which adds roughly 15 percent additional active string length. It can’t be as stable as the shorter headless, but 15 percent sounds like something one can live with. Still, there are typically two other parts on a headstock that have way more influence on tuning stability: the nut and one or more string trees. Both add friction to the strings, hindering them from equaling out different tensions.
You can test this yourself by bending a string. If it’s flat after the bend, then there’s too much friction. Raising the string tree by loosening its screw will reduce the friction at both the tree and nut. Then if you can confirm that each nut slot is wide enough not to bind the string, there isn’t much more you can do, except lubricate the slots. You have many options for this task, including gun oil, pencil graphite, or Vaseline. The differences between these lubricants won’t be huge, so use what you have at hand, but be sure to apply it regularly. It doesn’t hurt to lubricate the bridge saddles at the point where the string contacts them, but saddles rarely cause problems.
Fig. 2. Lieber used rollers to adjust string alignment on the zero fret and also create the necessary downward pressure to hold the strings against it. Entwistle’s preferred headstock shape requires additional hardware to guide the strings into their respective tuners. Photo courtesy of Tom Lieber (lieberguitars.com)
Of course, different nut materials have different frictions. Graphite is the slipperiest nut material, and because installing a graphite nut is way cheaper than replacing all the tuners, it’s well worth trying. Ball-bearing roller nuts and saddles have long been available to guitarists, but only a few exist for bass. Mark King got one on his Jaydee bass—which John Diggins built back in 1978 in Birmingham, England—but even that had just one roller for the G string. Kramer made one for their DMZ aluminum-neck basses in 1979, but they located it behind a zero fret and used the rollers to adjust the strings’ side-to-side spacing.
Another bass with a roller nut is the prototype Explorer bass built by Tom Lieber for John Entwistle around 1981 (Fig. 1). Here, the rollers are used to set string spacing across the zero fret and also create the requisite downward pressure against it (Fig. 2). As you can see, Entwistle’s preferred headstock shape compels a rather unfavorable arrangement of the tuners, and the extra hardware required to guide the strings causes additional friction—the enemy of tuning stability. It’s another example of how fashion can override the practical benefits of pure functionality.

Learn how to clean and condition your guitar and discover why it’s crucial to stay on top of such routine maintenance.
The proper cleaning and conditioning of your instrument is critical to its health. Over the years, I've seen many extreme cases of guitars that were permanently damaged from neglect. Without proper care, a guitar will lose value and eventually become unplayable. However, it's not difficult to clean and condition a guitar—it simply takes a little time and effort. And that's a worthy investment: Keeping your instrument in top condition will save you a lot of money in future repairs.
Fig. 2. Not only does fretboard gunk look unattractive, over time it can damage your instrument.
As we play, dead skin cells, sweat, and dirt build up on the fretboard and collect around the frets. Not only is this unattractive (Fig. 2), but the moisture, acids, and salts in sweat cause the wood around the frets to deteriorate. This can cause dry rot in the fretboard, which results in loose frets and very expensive repairs.
Fig. 3. These frets have become corroded through neglect.
I can always tell if a fretboard hasn't been conditioned when I examine the frets. This is especially noticeable when I'm doing a refret. After I remove the old frets, I can see nasty gunk on the tangs and green corrosion all over the fret wire (Fig. 3).
Fig. 4. If you don't clean and condition your fretboard, it may crack.
Cracks are another terrifying byproduct of not conditioning your fretboard (Fig. 4). When sweat evaporates, it can dry out the fretboard and cause it to crack.
Fig. 5. If they're not cleaned regularly, pickups, potentiometers, and switches can become corroded by the salts and acids in sweat.
A guitar's electronics can also suffer from dead skin cells and sweat. When acids and salts build up on a pickup, they can corrode the coils and magnets and cause the pickup to fail. These corrosive materials have the same effect on potentiometers and switches (Fig. 5).
Many string and accessory manufacturers offer conditioners for your guitar. But be aware that most of these products, including lemon oil, contain harmful chemicals and solvents that will damage your guitar's wood and finish. Avoid anything that contains d-Limonene, alcohol, or silicone.
Derived from oil extracted from citrus rind, d-Limonene contains natural acids. These acids can act as a solvent and break down finishes and cause the wood around the frets to deteriorate. Alcohol dries out the fretboard, bridge, and other unfinished wood, and can cause cloudiness in certain types of finish. Silicone prevents the wood from breathing and can cause the finish on your guitar to become hazy. It's also very difficult to remove.
Fig. 6. When wood isn't sufficiently humidified, it can dry out and crack. This guitar back has seen better days.
Controlling humidity is another important aspect of guitar care. When a guitar gets too dry, the wood cracks (Fig. 6). Conditioning wood certainly helps prevent it from cracking, but it's also a good idea to use a humidifier. New guitars tend to be more prone to humidity cracks than older instruments. Here's why: Most older or vintage guitars were made from air-dried wood. This wood was dried out over several decades, and during this process any pieces that cracked were culled out. The older harvested wood gets, the more stable it becomes, but it's a lengthy, painstaking way to dry wood. Modern guitars are primarily made from kiln-dried wood. Kiln drying is designed to speed up the aging process, but only time can truly age a piece of wood. Guitars made from kiln-dried wood are more susceptible to changes temperature and humidity. Maintaining a guitar-friendly humidity level helps prevent wood from cracking, and we'll discuss how to do this in a moment.
Cleaning and conditioning the fretboard. We'll start by cleaning the fretboard, and the first step here is to remove the strings. Yes, all of them! People often say, “Won't removing all the strings at the same time damage the neck?" The fact is, it won't. Wood has an excellent memory, so you don't have to worry about removing all the strings to service your fretboard. Luthiers do it all the time.
There are several ways to clean a fretboard, and one approach is to use 0000 steel wool. This works great, especially when you want to make your frets shine, but it makes a big mess. Caution: Do not use steel wool on a maple fretboard that has a glossy finish. Rubbing steel wool on any finish will make it hazy.
If you decide to use steel wool, use only 0000 grade. This is the finest steel wool and will not damage the fretboard or frets. If you're cleaning an electric guitar (or an acoustic with a magnetic soundhole pickup), cover the pickups with painter's tape to prevent the steel fibers from collecting around the pole pieces. These very fine steel fibers can cause a pickup to corrode, and they also cause noise if they contact the strings.
Fig. 7. If you opt to clean your fretboard and polish its frets with 0000 steel wool, remember to vacuum up the fibers that inevitably shed during this procedure.
Apply a fretboard conditioner to the fretboard and gently rub the conditioner into the wood with the steel wool pad, turning it frequently. Move across the fretboard, cleaning the wood between the frets, and then work the pad along the side of each fret. Once the fretboard is clean, run the pad up and down along the top of the frets to polish them.
After cleaning the fretboard with steel wool, use a vacuum to carefully remove the steel fibers that inevitably shed from the pad (Fig. 7). Avoid getting the fibers on the guitar's finish, as they can scratch it.
My preferred method for cleaning the fretboard is to use an old toothbrush and Planet Waves Hydrate, a type of fretboard conditioner. This approach is less messy than using steel wool, but it's important to note that Hydrate is only for dark fretboards—don't use it on maple 'boards.
Fig. 8. An alternative to steel wool: Clean the wood with a toothbrush and fretboard conditioner.
I like using a toothbrush because you can scrub all you want without damaging the wood or the frets. Simply spray Hydrate onto your fretboard and work it into the wood and around the frets with the toothbrush bristles (Fig. 8). Once the gunk is loosened, wipe it off with a paper towel. Also be sure you wipe off any excess conditioner to prevent it from coating the strings.
But the toothbrush technique won't polish the frets. If you're not too keen on using 0000 steel wool to do this (and I don't blame you), Planet Waves makes a product called the Fret Polishing System. Basically, it's super-fine polishing paper that's packaged with a protective stiff paper template that covers the wood while exposing the fretwire. The template fits medium or jumbo frets and you can use the kit on maple or dark fretboards.
Fig. 9. Planet Waves' Fret Polishing System includes super-fine abrasive paper and a guard to protect the wood.
Simply lay the template over the fretwire and polish the frets until they glisten (Fig. 9). The kit works great and there is little mess to clean up. But even with this system, you'll want to vacuum the residue off the neck left by the polishing paper.
Fig. 10. Like the fretboard, an acoustic guitar's bridge needs to be cleaned and conditioned.
Cleaning and conditioning a bridge. It's very simple to clean and condition the bridge on an acoustic guitar. Remove the bridge saddle and then scrub the bridge with a toothbrush and conditioner (Fig. 10). Use cotton swabs to clean inside the saddle slot. When the gunk is cleaned off, wipe down the bridge with a paper towel. That's it!
Fig. 11. Filth can build up on a bridge and its saddles. When hardware gets this dirty and rusty, you'll need to disassemble and clean it with WD-40 or 3-in-One oil.
Cleaning the hardware. Sweat is a big enemy of hardware because its acids and salts corrode the metal plating and attract dirt that clogs up any moving parts. In extreme cases, a guitar's bridge (Fig. 11) and tuning keys (Fig. 12) can begin to rust. Cleaning these important mechanisms keeps them looking good and functioning at their best.
Fig. 12. If left on metal hardware, sweat can eat right into the plating and cause rust.
For cleaning metal hardware, I've had success with 3-in-One oil and WD-40. Remember that these products are only safe on metal, so avoid getting them on the fretboard or finish. I typically remove the hardware to clean it with an old toothbrush and then carefully wipe it off before reinstalling.
Cleaning the finish. When cleaning your guitar's finish, avoid furniture polishes like Pledge, which contains lemon oil, or products that contain d-Limonene, alcohol, solvents, or silicone. All of these will damage the finish over time. Sweat is another finish-eater because it causes lacquer to soften and break down.
Water actually works well to clean a guitar finish. Use a slightly damp micro-fiber cloth to wipe away dust and grime, and rinse the cloth frequently to remove any debris. As for a good polish, I only use pure carnauba wax, which is safe for most finishes.
The Issues
Before we discuss how to clean and condition a guitar, it's important to understand where the potential problems lie and why we need to address them.
Two important components to clean, condition, and humidify are the fretboard and bridge. This is crucial because they are typically made of unfinished or untreated wood. Maple fretboards are an exception because they have some type of finish and therefore just need to be cleaned, but not conditioned. Rosewood and ebony fretboards and bridges must be cleaned and conditioned to prevent sweat and dirt from damaging the wood. A clean fretboard not only looks great (Fig. 1), but it feels great under your fingertips.

Controlling Humidity
Once your guitar is clean, you'll want to protect the wood with some type of humidifier. For a guitar that's stored in its case, I recommend the Humidipak from Planet Waves. It's a simple, accurate, and effective way to maintain the ideal humidity for your guitar. If you keep your guitar out in a studio or living area, try running an ultrasonic or warm mist humidifier in that room. For most stringed instruments, the optimum humidity level is 45 percent.
