Fulltone OCD Obsessive Compulsive Drive
Fulltone · pedal
The Fulltone OCD Obsessive Compulsive Drive is a boutique overdrive pedal known for a warm, full, genuinely tube-like response that bridges the gap between overdrive and distortion rather than sitting cleanly in one camp. Its drive control ramps smoothly from dirty, harmonically rich overtones into fuller saturated distortion, and it responds strongly to pick attack and guitar volume the way a real amp does. An HP/LP switch shapes the voicing: HP pushes more distortion with a pointed, cutting midrange, while LP is subtler and lets more of the amp's own character through. It suits players wanting an amp-like, dynamically responsive drive that can cover both classic-rock overdrive and heavier distortion tones from one pedal.
