I don't imagine there are many bass players looking on here for gear, but it's worth a shot. This is a great little bass overdrive! I've had it for years and it's the best for the price (which hasn't dropped at all and is close to $100). Boss pedals are tough and won't shit out like DigiTech pedals are notorious for doing. The ODB-3 has five knobs: Level, EQ (High and Low), Balance, and Gain. It works via 9V battery or AC Adapter so you can use it as is or plug it into your pedal board's power system. It's a little dusty around the knobs and has a road worn look (you do step on the thing). Looking to get between $50-$60 for it. Hit me up if you or anyone you know is interested.
