Fulltone OCD

Fulltone · pedal

The Fulltone OCD, or Obsessive Compulsive Drive, is a popular overdrive designed by Mike Fuller that uses MOSFET clipping to deliver a tube-like, amp-in-a-box character. Its controls include Volume, Drive, Tone, and an HP/LP switch that toggles between a brighter, upper-midrange-forward British voicing and a flatter, more transparent American flavor. Known for firm low end, strong output, and exceptional touch sensitivity, it covers light, dynamic breakup through thick, saturated rhythm and lead tones while staying clear and defined. Many players use it as both a primary overdrive and a loud clean boost. It is widely used across blues, classic rock, hard rock, and indie, valued for its responsiveness to pick attack and guitar volume and its ability to push a tube amp harder while retaining note clarity even at maximum drive.
