Xotic Effects USA Custom Shop MB BB Preamp- $100 shipped CONUS Price is firm. Instead of listing it higher and taking offers or doing price drops, I'm just listing it at the lowest price I'll take. You won't find it cheaper. If you do, let me know. Got this in a trade and don't need it. Outstanding condition. The BB preamp by itself is a great preamp, clean boost, and can get pretty dirty. This is the custom shop version that adds a mid boost control. If you have trade offers I'll consider them.
