The Warm Audio Warmdrive is modelled after a legendary 'amp-in-a-box' overdrive pedal that has earned its place on the pedalboards of numerous guitar legends, offering a truly unique drive character. For this purpose, only original components are used, including carefully selected parts such as 2N7000 MOSFETs, an NE5532 op-amp, and other classic NOS components. The pedal features a traditional four-knob layout with controls for Volume, Tone, Gain, and Voice. It can be powered by either a 9V battery or an optional 9V DC power supply.
