From the vendor
Rat is one of the most famous distortion effects. It has been accompanying rock music for over 30 years and is still eagerly used, also for the bass guitar. Quite a lot of gain, a lot of harmonics, when plugged into a decent tube amp, it can break even at a low volume. A must for every rock fan.
PCB. Dimensions: 43mm x 34mm.
