 A single-knob boost with an impressive 28dB of gain and a subtle character that compliments most guitar and amp combinations. Enhanced by the addition of TeaserMode switching; Grindstone’s system by which the single footswitch operates as both latching (traditional on/off) and momentary (on when pressed). The player determines how it operates based upon how long the switch is pressed. Switch it on and off normally, or press and hold for momentary operation.
