Fuzz Pedals
A fuzz pedal gives you a gritty, gnarly sound.
Scientifically speaking, a fuzz pedal alters your sound wave until it is almost square and adds overtones.
It is a more intense than a distortion pedal.
Fuzz pedals are available for electric guitars and bass guitars.
You will find fuzz pedals for both bass and electric guitars from brands such as MXR, Electro-Harominx, Wampler, and EBS.
