Benson Amps Preamp
The circuit is based on the 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!
9VDC Boss style adapter or battery 50ma
