The Cumulus Overdrive project is a clone of the Overdrive II / OD-855. This pedal was first released in 1977 and was a precursor to the Tube Screamer. However, it actually has more in common with an MXR Distortion+ or DOD 250.

This project is an exact copy of the original, but allows for an optional diode switch mod. While the original uses germanium clipping diodes, this board includes space for a switch and second set of clipping diodes if you?d like to experiment. There?s also an optional ?Softness? trimmer to adjust the clipping threshold of the mod side of the switch, and if you use a center-off toggle switch you can get a third ?diode lift? or ?comp-cut? mode.

This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 3 knobs for 6,3mm shaft separately.

This project is by Aion Electronics, in collaboration with Musikding. If you have any problems with the contents of the kit, please contact Das Musikding (Klaus). Since the modifications require some basic knowledge, this project is rather for more experienced builders.
