When it comes to amp-like overdrive, few guitar pedals rival the Fulltone OCD. Its unique — and revolutionary — combination of MOSFET transistors and voltage-controlled clipping not only sounds remarkably tubelike, but it also delivers extraordinary touch sensitivity and incredible dynamic response to your picking hand. The OCD boasts a streamlined, 3-knob control set for intuitive operation, alongside a versatile HP/LP switch that toggles between British-style tones (High Peak) with an upper-midrange push and more transparent, American-flavored tones (Low Peak). Additionally, the OCD’s Class A discrete 2N5457 JFET input stage bumps up the pedal’s impedance for increased dynamics and musical interaction with your guitar’s pickups. You also get a premium output buffer, providing you with consistent tone regardless of the pedal’s position in your signal chain, and selectable Enhanced Bypass or true bypass switching. From its tube-inspired MOSFET clipping to its hyper-responsive feel, the

Fulltone OCD Overdrive Pedal
Overdrive Guitar Pedal with Volume, Drive, Tone, and HP/LP Controls
Amp-like Grit Meets Incredible Touch Sensitivity
When it comes to amp-like overdrive, few guitar pedals rival the Fulltone OCD. Its unique — and revolutionary — combination of MOSFET transistors and voltage-controlled clipping not only sounds remarkably tubelike, but it also delivers extraordinary touch sensitivity and incredible dynamic response to your picking hand. The OCD boasts a streamlined, 3-knob control set for intuitive operation, alongside a versatile HP/LP switch that toggles between British-style tones (High Peak) with an upper-midrange push and more transparent, American-flavored tones (Low Peak). Additionally, the OCD’s Class A discrete 2N5457 JFET input stage bumps up the pedal’s impedance for increased dynamics and musical interaction with your guitar’s pickups. You also get a premium output buffer, providing you with consistent tone regardless of the pedal’s position in your signal chain, and selectable Enhanced Bypass or true bypass switching. From its tube-inspired MOSFET clipping to its hyper-responsive feel, the Fulltone OCD is one of the most distinctive overdrives around, packing amp-like grit and expressive nuance into a compact stompbox.
Note: The Fulltone OCD requires a negative-center 9- or 18-volt power supply, depending on your desired amount of headroom. For more information, please call your Sweetwater Sales Engineer.
Enhanced Bypass preserves every nuance of your playing
Fulltone’s obsession with tone drove the company to scrap conventional buffered-bypass designs and, after years of R&D, invent Enhanced Bypass — a Class A FET arrangement that preserves every subtle nuance of your playing. Rather than the unity-gain FET buffers found in most pedals, the OCD’s Class A FET stage, in the words of Fulltone founder Mike Fuller, “returns all the dynamics,” delivering an expressiveness and touch sensitivity you simply can’t get from traditional circuits. And when you crave absolute transparency, an internal switch flips the OCD into true bypass mode, giving you the choice between cutting-edge buffering and pedal-to-amp purity.


Built to inspire: Fulltone’s legacy of sonic excellence
Fueled by a lifelong passion for music and an uncompromising pursuit of world-class tone, Mike Fuller founded Fulltone in 1993, setting a new standard in the world of guitar effects. From iconic overdrives to studio-grade modulation, Fulltone pedals have earned their place among the most respected tools in modern music. Crafted with precision for both live performance and studio recording, each Fulltone product is a testament to reliability, innovation, and sonic excellence. Sweetwater stands proudly behind these American-built pedals. They’re not just built to inspire; they’re built to last a lifetime.
