Benson Preamp is a preamp pedal based on the circuit of the Benson Chimera 30 watt guitar amplifier. Instead of tubes, this pedal has FET transistors. The result is an incredibly amp-like and versatile clean boost that doubles as an overdrive pedal with rich overtones and a very musical EQ.
There are only four buttons on the pedal that allow you to colorize the sound to your liking. As a boost, this pedal colors your guitar signal a little bit in the midrange, otherwise it seems like your notes sound a bit closer and jump more out of your amp. Open up the drive a little more and you'll get a nice, clear overdrive with a bit of compression without sounding unpleasant. Open the drive even further and you even enter the territory of distortion and fuzz.
