A little more about this special run :::

  • Hand-selected & tested NOS 2N2222A transistors for unrivaled tone  
  • Stunning UV-printed artwork by Sylvia Massy—legendary record producer and artist (Tool, System of a Down, Prince, Queens of the Stone Age, and more)  
  • 60 units available now, each hand-assembled and hand-numbered. 

Designed for bass, a favorite for guitar, this incredibly sub-frequency-preserving unit will hold on to the lowest lows like no fuzz ever heard before.

It features a gentle gate for silencing your instrument between notes or phrases, and has an EQ control that smoothly selects between more bass and more treble.

Pedal Dimensions (LxWxH):  4.70" x 2.38" x 1.82"
