The OCD has received many slight tweaks over the last 12 years, often incorrectly identified as version 2, Version 3, V4, etc. In reality there has always been only one version Version 1, with very slight variations after that making them V1.1 through V1.7. On 6/15/2017 we released a very new OCD, different enough that it warrants a V2 designation, an explanation and warrants a trip to your favorite dealer to give it another listen. Not a subtle change when turned onÉnot a subtle change when turned off (in E.B. mode).

 

Sonic changes to OCD V2. There is an output buffer (when pedal is turned on in True-Bypass mode, or always when in Enhanced Bypass mode) which eliminates it from being influenced by effects that came after it. Translation, your sound remains consistent regardless of placement in today's more complex signal-chains, loopers, and pedalboards. This buffer also had a positive effect on the sound, it reduced loading on the pedal's hard-clipping stage, allowing more sustain of both the sound and the overtones.

Class A configured discrete 2N5457 JFET input section, raising the input impedance to 1 mega ohms (previously 330K) and increasing the dynamics resulting in significantly better interaction with both single coil and humbuckers.

Internal switch to choose between Enhanced Bypass TM & True-Bypass, and with no popping sound in either mode. No other company offers EBÉwe invented it.

Enhanced Bypass! Configuring both of the switching FET's Class-A! By configuring a FET for gain (also referred to as wiring it Class-A) all the dynamics return (and then some), even if you only configure it with the slightest amount of gain, in this case: 0.3 to .06 dB.

People rave about old EP-3 Echoplexes and Ep-3 type boosters, and although they know that they love what it does to the guitar's sound, they can't explain why. It's because of the Class-A FET preamp! With a Class A FET the dynamics get amplified, allowing an even greater range of expression than if you were playing through a guitar and just one cable straight into your amp. The downside with EP-3 preamps is that they throw the signal OUT-of-phase, boost treble, and cut bass. Fulltone's EB the signal exits the pedal IN-phase and doesn't change the EQ at all.
