The Diezel Zerrer is a versatile 2-channel preamp and distortion pedal, offering aggressive tones reminiscent of Diezel amplifiers. It features two independent channels (clean/dirty and high gain) and can be used as a distortion in front of an amp, in a loop, or as a preamp. It also includes stereo aux input for backing tracks, stereo headphone output for practice, effects send/return, and a compensated output for direct recording. It's a boutique effect, perfect for guitarists seeking high-quality distortion.
