This is the dual version of the AC Booster, giving you two channels of boost/drive and a bunch of different ways to get your amp popping You can stack the boosts in either direction, there's a powerful EQ, there's a clipping toggle... heaps of fun to be had. Get in dialled in right, and as per usual with Xotic stuff: it's gonna sound terrific.
