NOS Peavey BAC-2 Bi-Amp Bass Chorus pedal. From what I can tell these were expensive pedals when they came out in the late 80's (this one's copyright 1987 like me!) and was untouched for years, maybe sampled once or twice in a store. The pedal provides a subtle, creamy sustaining chorus and adds a gentle mwah to my fretless through my GK. It's the same tone I was looking for in the chorus on my Peavey Mark VI and hit it right on the nose. Wonder why? The pedal is very solid, NOS in box with manuals, shipped for $30 including Paypal fees. Sounds great, looks great, and I'm pretty sure these are hard to find! Even the side of the pedal says the SALE PRICE is $82.50. Wonder what the original retail was?
