The Voodoo Lab Sparkle Drive pedal gives you the dynamic punch of a clean amp, and the sustain and warmth of an overdriven amp, all in a single stompbox. Sparkle Drive"s unique Clean control lets you blend its overdrive circuit with a boosted clean signal for a rich, layered guitar tone. With the Clean control off (fully counterclockwise), the overdrive circuit has the same classic tones as a vintage 808. With the Clean control all the way up, you get a super transparent, 100% clean boost with tons of output for driving the front end of your amp. Just spend a few minutes dialing-in the Clean control with your setup, and you"ll find a sweet spot that no other single effect pedal can deliver. The Voodoo Lab Sparkle Drive features true bypass switching, a heavy-duty metal switch and on/off status LED. Hand built in the U.S.A. and fully backed by a 5-year warranty.Multiple, layered amp sounds - one clean, one overdriven Overdrive circuit delivers vintage 808 sounds 100% clean boost circuit with tons of output True bypass switching with LED Hand built in the U.S.A.
