The Reanimator Reverb is the reverb pedal that we made because we wanted a simple, no-frills reverb in a small package. This transparent reverb pedal has plenty of headroom and reverb for days. Our favorite feature is the tone control which we feel all reverb pedals should have. We see digital delays with "analog" mode which cuts the treble and that is exactly what our Tone knob does. This allows you to dial in a more ambient, natural sounding reverb that swells around you. In addition we also offer our a 3-knob version with the addition of a Decay knob to determine how long the reverb fades out. Think longer times for surf rock and shorter decays to prevent a distorted guitar from getting muddy. This pedal runs on 9V DC only and has no battery option.
