The Voodoo Lab Sparkle Drive is an overdrive pedal featuring a unique “clean” control. It’s overdrive circuit provides the same tone as a vintage ‘808. We included the original JRC4558 op-amp for authenticity, but upgraded other components such as using high precision metal resistors and modern polyester film type capacitors. You’ll hear these higher grade parts in a tighter midrange, crisper highs and overall better note definition.

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 clean boost and blending circuit use a studio grade op-amp for crisp and super transparent sound without added noise.

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 100% clean boost.

Gain: This sets the gain level for the overdrive sound only. It has no effect on the “clean” signal. Use low settings to warm up and compress your tone. Turn it up for additional sustain and saturation.

Tone: Turn it up for a brighter sound, down for darker. It is for the overdrive only and has no effect on the “clean” signal.

Clean: This blends the boosted clean signal with the overdrive. All the way down is overdrive only. All the way up is clean only. In between is a blend of both the clean and overdrive.

Volume: This sets the output level. Set as desired! Plenty of juice is available to overdrive your tube amp.

The Voodoo Lab SparkleDrive is powered by a single 9V battery. To replace the battery, remove the four screws which secure the bottom cover.
