Maxon OD820 Overdrive Pro

From Maxon:With plenty of gain, a super-musical tone circuit and a transparency rarely found in a pedal, the OD820 takes Maxon's legendary 808 circuit and launches it into the 21st century.The OD820's voltage doubling circuit adds gain, girth and grit without desecrating your existing tone. Imagine the classic 808 sound with more output, more bottom and more drive and you've pretty much summed up the 820's sound.The circuit's additional headroom gives your playing a fluid, effortless feel: Notes jump off the fretboard with a noticeable yet controlled sustain. Though capable of heavier-than-usual overdrive, the OD820's dynamic response is amazing and the pedal cleans up beautifully by rolling back your guitar's volume control.The dual-ganged Drive pot blends clean and dirty tones, creating stunning clean solo boosts at lower settings and a buttery, light overdrive at high noon. Max it out for a full-bodied overdrive that's saucy and saturated while still retaining clarity and openness.The Maxon OD820 - the quest for the ultimate overdrive ends here.
