The Rowin Gumble pedal is a mimick of the rare boutique Dumble amplifier overdrive. The Gumble features the typical Volume, Gain, and Tone control knob layout and comes with a two-way selector switch that lets you toggle between Normal and Bright modes. Its a smooth but powerful drive, well finessed, and proof that the size of the pedal doesn't matter.
