The Fuzzrocious Rat Tail is based on a well-loved distortion pedal with changes to make the circuit more usable on both bass and guitar. Three clipping choices gives the user very different tonal clipping options (silicon, no diodes, and LED). The double resistor mod allows you to fine tune your sound and control how the circuit clips by clipping more on just the highs, just the lows, or anything in between. It includes bypass footswitch, volume pot, tone filter pot, distortion pot, clipping 1 and 2 pots, diode toggle (silicon, no diodes, LED), and a 1590BB enclosure. It can be modded with a feedback loop and second distortion setting for an extra charge.
