I Got Wood
by Cullen James
Wood for your guitar. This is a highly complex and emotionally charged topic for guitar players and builders. Some people try to use physics to explain the uses of wood, others use mojo. Some build for economy, others build for looks. I simply cannot go into all the ins and outs of this topic, there isn’t the space and I don’t have the time. Here, I’m only going to talk about the basics and only cover electric guitars.
The wood chosen for a guitar is pretty important for a variety of reasons. A wood’s strength is a primary concern. How well it can be worked – carved and shaped -- into the guitar is another. How the wood looks and adds to the aesthetics of the guitar is another huge issue. How wood affects the sound of the guitar is perhaps the most contentious issue and that’s where you’ll hear about the “mojo.”
All of the building materials for a guitar, wood especially, directly effects the vibration of the strings and their resonance -- which directly effects the quality of the sound. This is especially true of an acoustic guitar since you're hearing raw sound -- naked wood, as it were. In an electric, the pickup does all the work and it is (generally) not microphonic. That is, the pickup doesn't "pick up" the sound of the strings, it picks up the vibration of the strings. This vibration creates a signal in the pickup which is translated to sound.
Something that complicates building is that the same wood may not produce the same, consistent effects. You might think then that any wood of similar resonant frequency should create guitars that sound the same. Well, I don't know why, but it's not true. Anybody can pick up an Alder body Fender Strat and a Basswood body Strat and hear a subtle difference in tone and color even though the two woods are very similar in grain, weight and resonant frequency. If you ever want to test this out for yourself a Strat is a great guitar to use, because they are essentially an assembly line, cookie-cutter product. One of them is going to be very similar to another.
What makes this subject even more complex is when you begin to realize that two guitars, using the same wood, with the same hardware and electronics and similar finishes sound different. Even wood from the same tree isn't necessarily the same. Some is denser, some has tighter grain -- it's a crapshoot. But there are some generalities and I'm going to list some of my favorites woods here and some of their supposed tonal qualities:
Quilted or Curly Maple: Quilted Maple is a rock maple tree that has a wavy or curly appearance. No one knows for sure why the trees get this look. Maple is a heavy wood and the non-figured rock maple is usually used in guitar necks. Quilted maple, along with it's cousin flamed or tiger-stripe maple, is used primarily as tops for guitars.
The majority of the guitar body will be made with a different wood like mahogany and the quilted maple will just be a cap. If the cap is thick enough, it will effect the sound of the guitar. However, there are lots of guitar companies that only use a thin maple veneer top. This looks pretty, but doesn't do anything to the sound. Thick maple caps can really brighten up the tone of a guitar.
This guitar is a beatiful example of quilted maple in use on a JET guitar. The figured maple really pops out once stained and polished. Depending on the color used it can look like flames or wavy water. Beautiful stuff.
Spalted maple: Spalted maple is actually wood that has begun to decay. The cool lines and firguring seen in the wood is fungus attacking the grain. This leads to spectacular looking lines and figures throughout the boards. It almost looks like someone has drawn on the wood, but this is all natural.
As with other figured maples, spalted maple is primarily used as a cap on a guitar body. However, spalted maple cannot really be used for anything else. It has a brittle structure and is not strong enough to be used for anything that could put strain on it. It looks gorgeous though, and you can get all kinds of figuring. This guitar is one of Ed Roman's Quicksilver bodies, and I think the spalt looks like a collection of fall leaves. But you can get figures that look like lightening strikes or just random lines. It's truly gorgeous and rare. The sound quality is similar to that of other maple caps.
Here is a guitar I really lust after. It's by Jaros Guitars. It's got most of what I love in a guitar; it has an ebony fretboard, a cool but simple fretboard inlay, it's walnut and it has a tune-o-matic bridge. If the hardware was chrome or nickel I'd probably have to rob a bank.
There are literally thousands of species of wood out there that have been used for guitar manufacture. I could write a book on it, as others already have.
As much as I like listening and playing to guitar, I really love looking at the art that they are. I’d hang ‘em on the wall before I’d hang a Picasso.
