Benson calls this a Preamp because it is! 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!
