So the Boss ODB-3 is well-loathed around here, with good reason. BUT with this mod it's a really nice overdrive pedal. You get a couple different flavors with a 3-way toggle and the overall sound is NOT fizzy anymore. It's thicker, juicier, meatier all around. I'm not in bands where I need distortion sounds and I have about 10 other pedals if I really needed them. It gets a tiny bit squealy at high gain settings, but this pedal really excels at light drive anyway. Monte Allums Site DEMO! $50
It's beat up on the outside but beautiful on the inside.
