Voodoo Lab Sparkle Drive

Another request from quite a few people and I suspect this will be another of those pedals which is equally popular with the bass guitarist.  Info from the manufacturer about their original:

Voodoo Lab Sparkle Drive is an overdrive pedal
featuring a unique “clean” control. Its overdrive circuit provides the
same tone as a vintage ‘808. Then the clean control blends back in a
boosted direct signal. This restores the attack and feel which is lost
in a highly compressed overdrive circuit.
The Sparkle Drive utilizes the same
concept as layering two amps, one clean and the other saturated. Of
course with the clean control turned down, you get a classic overdrive
tone. All the way up, it provides a super transparent, 100% clean boost.






Modded version with clipping switch:
I don’t know exactly what the official “Mod” version is, but this offers a 3 position switch to choose between stock setting with the 1N4148’s, a more compressed setting with the LEDs (or try germanium diodes if you prefer), or the centre off position to give you a clean boost “diode lift”.
