This is a Germanium preamp designed around a rare NOS OC139 black glass transistor with the intention of driving your amp harder or pushing your clean amp's preamp into the world of drive.
A highly recommended and excellent preamp pedal.
- Level: Adjusts the output level by setting the bias voltage of the transistor. A small amount of noise while dialing this in is perfectly normal.
- Tone Toggle: “Treble” for a brighter, more resonant tone and “Full” for a warmer, bass-heavy push.
- 4.625″ x 2.5″ x 2.25″ with knob
