From Benson: We call this our Preamp because it is! The circuit is based on the our Chimera 30 watt guitar amplifier, but substitutes FET transistors for the vacuum tubes. The result is an extremely amp-like and versatile clean boost/overdrive/fuzz pedal that imparts rich harmonics and a very musical EQ to your signal chain…truly a Chimera in a box! Power requirements: 9VDC Boss style adapter or battery 50ma (not included) Controls: Gain, Volume, Treble, Bass.
