The Serf is a hand-wired valve (tube) boost pedal, utilizing a 12ax7 tube running at high voltage. A 12ax7 tube contains two gain stages. The first gain stage is a voltage amplifier and boosts the guitars signal, while the second stage is wired as a DC coupled cathode follower, providing a low impedance output. Suitable for general boosting duties, it excels at pushing amps and OD pedals into higher gain. The Serf Boost is a clean boost - it does not clip easily itself.
Includes original box and power supply.
