Perfect condition. All knobs, switches, power and battery connectors work perfectly. Clean bottom with visible original serial number. Works from 9 to 18V for more headroom.

For many players, the V1.7 is the "holy grail" version. The earliest versions (V1.1 to V1.3) are rare but can be incredibly harsh in the treble or overwhelmingly boomy in the low-end. The highly popular V1.4 fixed the bass issue but introduced a slightly scooped midrange.

In mid-2017, Fulltone moved to Version 2 (V2), which fundamentally changed the pedal by adding a permanent output buffer and altering the internal circuit configuration. Many tone purists dislike the V2 because the buffer changes how the pedal reacts to your guitar volume and other effects.

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.
