 Some bassists also use octave pedals to generate extremely low pitches or bass overdrive pedals that produce a fuzzy, distorted sound.Although these effects function in the same way as regular electric guitar effects, a bass tech must be familiar with the settings and the resulting sounds and tones that are most often used by bass guitarists.A guitar tech who is in the first stages of learning to become a bass tech may know how to set up the bass effects from a technical point of view, but it may take a little longer for them to learn which compressor settings, for example, are associated with different funk or metal styles.
