Description
The 12AU7PRE is a tube-driven preamp and booster pedal built by Lee Custom Amplifier. It uses a JJ Electronic 12AU7 ECC82 tube in its circuit. The pedal provides controls for Treble, Bass, and Volume, along with internal switches to adjust the frequency range of treble and bass. The signal path consists of amplification, tone circuit, amplification, and volume, designed to respond similarly to a tube amplifier. The pedal does not include a buffer mode. Power is supplied through a 9V DC input, which is internally boosted to 100V for the tube.
