The Prehistoric Dog is a solid state preamp pedal inspired by the Sunn Beta Lead and Beta Bass amplifier preamp circuits. It is designed to deliver aggressive, raw distortion tones with strong midrange presence and tight low end. The pedal is intended for use with guitar, bass, and other amplified instruments. It can function as a standalone distortion unit or as a full preamp when run into a power amp or recording interface. The circuit is based on classic solid state amplifier topology rather than tube emulation. The pedal is hand built in the United States by Berserker Electronics.
