Improvements over the original

• Booster
Optional transparent boost is always a useful feature. It makes your overdrive pedal not a one-trick pony anymore. The one-knob booster is switchable by additional, independent footswitch. You can also use the booster with your Driver off. Treat it as two independent pedals in one box.

• Effects Order toggle switch
Do you remember about two effects in one box? You can arrange them in the order you want! The Booster before Driver will boost the gain and increase the saturation. The Booster after Driver will boost your output volume. How cool is that?

• DRY knob
This is your parallel dry signal control. You can mix it in to your OCD-overdriven sound. Mixing distorted signal with clean signal opens up completely new sonic territories. Now you can achieve the same distorted punch without loosing clarity. Despite high saturation, you can hear every single note perfectly. It’s especially useful for playing chords or rock riffs. This solution was inspired by professional music production techniques. Surprisingly many rock songs have a clean-ish guitar mixed in to improve the sound clarity. At 0% of DRY knob rotation you get no dry mixed in. At 50%, the dry signal is unity gain. By turning the knob even further, you are boosting your mixed in dry signal. Crazy!

• VOICE knob
Every single overdrive pedal has it’s unique character. At 50% of VOICE knob rotation you get your original OCD character. Turn it left for brighter sounds that sit better in the mix. Turn it right for darker, balanced sound with deeper low-end.

• STOCK / MOD toggle switch
This mod takes one of the N-MOSFET clipping transistors out of the circuit, so the sound gets a little smoother.
