Fulltone was founded in 1991 by Michael Fuller. They make quality, rich, fat-sounding tone tools with a reliable build quality. All Fulltone effects carry a 5 year warranty and are built for (and by) musicians. The OCD is the biggest selling boutique overdrive ever!

The Fulltone Obsessive Compulsive Drive (OCD) is an extremely open sounding Overdrive/Distortion circuit that differs from other overdrives in that it has a good bit more Dynamic-Range…meaning the difference between picking soft or picking hard will actually yield a more natural and wider range of distortion (with less compression) than traditional diode-clipped overdrives. The OCD also creates complex overtones without changing the inherent tone of whatever amp and guitar you’re playing through, in the process lifting off that blanket other drive pedals can put on your signature sound.

The OCD accomplishes its tube-like distortion through the unusual combination of overdriving its JFET opamp, and then hard-clipping with a pair of MOSFETs later on in the circuit. This topography did not exist in a pedal prior to the OCD, and the circuit works very well with a vast array of guitars and amps. Because of its large amount of available output volume, the OCD works great as a booster in front of amps to goose them into submission, as well as through Master-Volume amps to drive them much harder than most OD‘s can, but it also excels at creating its own distortion with all the chime of a Class A amp and its complex array of overtones. The OCD gives you the feeling that your amp is Cranked at even living room volume so Clean playing is more dynamic and dirty sounds still have the ringing overtones. The OCD’s can access a slew of other in-between sounds by simply turning up or down your guitar’s volume control, in fact, no other pedal “cleans up” like the OCD. Try it at 18VDC and you get another level of dynamic range and clarity. I recommend using the Fulltone IPS-18 for 18volt operation (for use in all countries) as it is regulated and dead-quiet. Avoid other “switching type” power supplies, as we get a lot of reports that the majority of them hum or create strange synth-like noises. Ours is quiet.

There are a lot of OD’s comparing themselves to and stealing from the Fulltone OCD, and that’s to be expected when you’re the best selling handmade overdrive of all time. There are many out-and-out clones of the OCD, and that’s some form of a compliment I suppose, but I’d like to personally thank you for buying and supporting the original…the one and only OCD.
This final version of the OCD (V2) has some exciting improvements over previous versions:
Class-A wired JFET input raising the impedance from all previous OCD version’s 330K to 1 Mega ohm, thus interfacing better with all types of pickups, isolating the input from everything coming before the OCD in your signal chain, and giving the pedal more touch-sensitivity than any other OCD version, or any other pedal for that matter.
Buffered output completely isolates the pedal from the influence of everything following it in the signal chain and allows much more sustain and overtones than previously OCD’s, even at lower distortion settings.
Internally selectable “True-Bypass” (TB) or “Enhanced BypassTM” (EB) switching. EB, a Fulltone innovation, is a vast improvement over the industry-standard, dynamic-robbing unity-gain JFET or Bi-Polar buffers used by other companies. Fulltone’s EB doesn’t have the out-ofphase issue and tone-loss inherent with most circuits either. True-Bypass was great back when we were only using a few pedals. But things have changed. Simply placing the V2 OCD (bypassed, in EB mode) in your signal path will recoup all of the lost tone and picking dynamics that standard buffered & TB pedals and cables cause.
