Fulltone CS-OCD-GE Custom Shop Germanium Overdrive Guitar Effect Pedal

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 DiodesA 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 PotEarliest OCDs had an audio taper volume pot which changes where (during the volume knob’
