The MXR CSP203 La Machine is a Custom Shop fuzz pedal delivering a classic, aggressive vintage fuzz character suited to rock and psychedelic playing, with an octave switch adding an upper octave to the signal for extra harmonic complexity and versatility. Running on standard 9V DC power, it's built for players wanting a vintage-inspired fuzz voicing enhanced with switchable octave-up textures beyond a standard single-mode fuzz circuit.
