The SansAmp Classic is a guitar and bass preamp pedal designed to emulate the sound of tube amplifiers without the need for external effects. It was first introduced in 1989 and has since become a staple in the music industry for its versatility and unique sound. The pedal features a three-position input switch that allows users to select between different preamp styles, such as Marshall-style, Mesa Boogie-style, and Fender-style.
