The Fulltone 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 the guitar and amps that you're playing through, in the process lifting off that "muffled blanket" other drive pedals can put on your sound.

The OCD accomplishes its tube-like distortion through the unusual combination of overdriving its JFT opamp and additionally with the use of hard-clipping via a pair of MOSFETS to "Vref." This method did not exist in a pedal prior to the OCD, and you'll find that this design 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 overdrives can, but it also excels at creating its own distortion. The OCD can give the impression 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.

The Custom Shop OCD-Ge has some exciting differences from other OCD versions:

Germanium Diodes
A pair of matched Germanium diodes are used in conjunction with the pair of Mosfets. This not only widens the clipping threshold, but the clipping takes on the "soft-knee" characteristics of the Germanium diodes, giving a tubey feel and enhancing octave-up overtones.

Audio (Log) Taper Volume Pot
Earliest OCDs had an audio taper volume pot which changes where (during the volume knob's rotation-sweep) the volume comes on. Fulltone went with an audio taper on this one because the CS-OCD-Ge is a bit louder than regular OCDs, and the audio taper allows you to find the right volume without having to be super-careful around the lower third section of the pot's roatation.

A More Open Sound
The softer characteristics imparted by the Germanium diodes allowed me to tweak some values to let through more highs, this results in more clarity without harshness when the tone control is turned up.

Closest to the original yet.


The sound of the OCD-Ge seems very much like the original version when it first came out - I wish I had kept that one. I have tried the OCD off/on for many years since and couldn't keep one on my board until now. The OCD-Ge sounds incredible.

Warranty does not cover any damage done to equipment that has been connected to Fulltone's products. Fulltone determines what constitutes "normal use" and also makes the determination as to whether the claim is "Warranty covered,"not the Dealer or the customer. Fulltone Musical Products Inc. is not responsible for and injuries and/or damages related to the use of their products.

Power Supplies: 5 year free replacement to original owner purchased through authorized Dealer.

Tape Carts (ETC-1 & ETC-2) 3 months: Limited Warranty: Fulltone guarantees the ETC-1 & ETC-2 tape cart to run for 3 months from date of installation only under the following conditions:
1) proof the cart was properly installed on a clean, well-maintained Fulltone TTE or SSTE by making a clear, close-up video of the Tape cart running after the install. Keep this video on file in case of any problems. This video will help us diagnose any other problems as well.
2) The cart must not have been damaged due to user-error. We will make the determination as to what constitutes "user-error."

Batteries: are not Warranty-covered.

Customer Troubleshooting: Warranty support is entirely dependent on the Customer's willingness to assist in troubleshooting. The customer agrees to furnish a clear video (cellphone video ok) representing the problem at hand, and we have provisions on our website to upload such videos. Refusal to submit such help or a video will result in instant disqualification for repair assistance. 90+% of "My pedal is broken... I want a new one NOW" emails result in the discovery that the item was either plugged in backwards, dead battery, the wrong power supply was used, another pedal in the customer's chain is actually the culprit, or the customer doesn't understand how to operate the device and how it's supposed to sound.

Shipping: Customer is responsible for all shipping costs unless there are extraordinary circumstances and Fulltone decides otherwise. This decision is made only by Fulltone, not the Dealer or Customer. There are no shop visits or drop-offs unless cleared & scheduled in advance. All items must be shipped to Fulltone via FedEx, UPS, US Mail, & DHL. We strongly recommend the customer follow the companies' packing guidelines to assure that they have recourse should the item become damaged during shipment. Fulltone is not responsible for any lost or damaged items during before, during, or after the shipping process.
