The More control goes from nearly clean to a medium gain overdrive when at maximum. This control adjusts the bias of the transistor, so you may hear a little noise as you turn the control. Don’t freak out; it’s totally fine. The gain characteristics are dependent on which diodes are chosen. When the Germanium diodes are selected, the Special Cranker delivers a softer, more rounded response with tamed highs and lower output, while the Silicon diodes add a brighter, more modern edge and higher output. Both are exceptionally responsive to playing dynamics and have excellent clarity. The Tone control gives the user full command over treble frequencies, cutting the highs when counterclockwise and adding a slight high frequency boost when turned clockwise. The Level control adjusts the output from nothing to nearly double at maximum.
