This is the first pedal released by Dropping Acid Pedal Etching. The #rip. is an LM386 op amp distortion that goes from mild to wild. With four modes at your disposal, you can achieve sweet distorted tones for your post rock band or rip your self into oblivion with the momentary feedback switch. Mode 1: Clean, always on preamp, boost Mode 2: "Normal" guitar or bass distortion Mode 3: Gain and Bass Boost Mode 4: All the GAIN and all the BASS. The voltage knob interacts with the distorted signal and will yield gated/ sputtery or broken amp sounds. The momentary feedback button will give you robot farts to high pitch squealies depending on the other settings on the pedal.
