Though the SansAmp technology by Tech 21 has given birth to many other pieces of gear, there's only one Classic. The SansAmp Classic is a distortion pedal with only four knobs that give rise to nearly countless permutations of tone or sound. Starting with three preamp styles, Marshall-style, Mesa-Boogie Style, and Fender-style, leading all the way to simple drive controls, including 8 super unique character modes, the SansAmp Classic demonstrates why it revolutionized Tech 21's entire product line. Smooth overdrive to the crunchiest distortion can all come out of this small box.
