The Use of Overdrive in Jazz Guitar

When most people think of jazz guitar, there is a certain sound they have in their mind; a dark, warm, and clean sound that emphasizes the middle frequencies and loses the high. Indeed, most jazz guitarist to this day spend at least some of their time with this general type of tone, and while it is not an altogether bad thing that a trademark sound has been established, there can be many benefits of a tonal expansion.

It is hard to pinpoint exactly how the classic jazz guitar tone began. It’s certainly not the default sound of a guitar and an amp, so there was a conscious decision to form a warmer and smoother sound. The best guess for the thinking behind this is that early jazz guitarists wanted to make their guitars sound more like pianos.

Pianos had been a part of jazz from the beginning, and part of the styles that led to jazz. Guitars, however, were not. It would make sense that the early guitarists wanted to blend their tones into the traditional jazz aesthetic by rolling off some of the guitar string sounds and getting a more pure tone.

There’s nothing dishonorable or fake about this. Chordal instruments have to play a certain role in a jazz group. They need to provide a full sounding harmony for the melodic instruments without getting in their way, and a less treble-ridden tone works well for this. Imitating the piano was a perfectly natural step for jazz guitar.

However, there were some early players that got away from this traditional sound. Grant Green was one of the first great jazz guitarists, and he used high levels of guitar overdrive in many recordings. It was in his solos that you would hear his tone really stand out, as guitar overdrive will always add some presence to a melody.

After Grant Green, other guitarists also used overdrive for various tonal expressions. On some of the more experimental Miles Davis records, the guitarist uses an overdriven sound to produce quick runs and effects that act as more of a background flourish than harmony or melody. This is the type of expanded playing capabilities that an overdrive pedal or overdrive from an amp can afford a guitar player.

In more modern times, players have shown that they are not afraid in the least to use guitar effects in their records and performances. Bill Frisell frequently uses all types of effects pedals to add to his performance, including looping pedals that allow him to play multiple parts over one another. John Scofield is well known for using a lot of overdrive and distortion as his main tone.

Kurt Rosenwinkel is a current guitarist who has steadily used more and more effects in his playing, and for different situations and recordings he will change up his tone. While he began with the standard jazz sound, he will now use overdrive, long delay, and tremolo for his basic tone.

More than this, the addition of effects like guitar overdrive to the jazz guitar world have spawned whole new styles of music that can all be called some sort of jazz fusion. Players like Allan Holdsworth are seemingly combinations of progressive rock and jazz, and they are no strangers to all the effects that rock guitarists use.

This expansion of guitar effects in jazz guitar is not insignificant. Jazz is not exactly a popular form of music, but when the jazz guitarists start sounding more like rock guitarists this gives them a path to many new listeners who stay away from the traditional jazz sounds. When a jazz player is soloing in an intense and distorted tone, the people used to rock solos have something to draw them in.

Jazz is in need of as many new fans as possible. More fans means more players can be supported, which means more competition in the music they produce, which leads to more high quality music being made. To avoid this because of some notion of tradition would be silly. It is valuable to preserve and document tradition, but not to be shackled to it.

The increased use of guitar overdrive and other effects in jazz guitar should have a positive effect on the popularity of jazz, and should keep the genre moving in new directions, and that is what jazz is all about.
