The Fulltone OCD (Obsessive Compulsive Drive) is a legendary guitar overdrive pedal known for its dynamic, amp-like tone and exceptional touch sensitivity. Designed with a MOSFET-based clipping circuit and Class-A input stage, the OCD reacts naturally to picking intensity, delivering expressive overdrive that cleans up smoothly with guitar volume changes.

A built-in HP/LP tone switch allows players to choose between two distinct voicings. High-Peak mode delivers a more aggressive, mid-focused character inspired by British amplifiers, while Low-Peak mode provides a smoother, more transparent American-style response. This versatility makes the OCD suitable for a wide range of guitars, amplifiers, and musical genres.

The pedal features a straightforward three-knob layout—Volume, Drive, and Tone—making it easy to shape sound quickly without unnecessary complexity. A premium buffered output and enhanced bypass circuitry help maintain signal integrity, ensuring consistent tone whether the pedal is active or bypassed.

Built in the USA with a rugged metal enclosure, the Fulltone OCD is designed for reliability on pedalboards, in studios, and on stage. Compact, durable, and tonally flexible, it remains a trusted choice for guitarists seeking authentic overdrive performance.
