From the manufacturer:
THEE Classic British Rawk tones period. Plexi/JTM, really anything this side of the ‘800_s. But the DRD is also perfect for the just breaking up, dynamic dirt sound that blends right into your amp and you can control with your fingers… and it has just the right uppermid push to sit correctly in a band mix – a real pro dirt pedal that feels real. 5- 15v
