OCD (Obsessive Compulsive Drive)

If any drive pedal rivals the Tube Screamer's legendary status, it's the Fulltone OCD. Released in 2005 and named for Mike Fuller's perfectionism, it revolutionized transparent overdrive.

The OCD delivers harmonically rich drive with the dynamic response of a cranked tube amp. Wide gain range covers low-gain blues crunch to Marshall-esque distortion. The HP/LP switch shifts between tighter high-peak and looser low-peak voicings.

True bypass, quality components, and that amp-in-a-box feel made the OCD a modern classic. It remains on countless professional pedalboards worldwide.
