The Marshall-in-a-box territory is pretty well trod, but this Xotic SL Drive pedal is a welcome breath of fresh air. For one thing, it�۪s tiny, so if you�۪re the type who already has eight or so pedals on your board, you most likely won�۪t have to boot anything to make room for it. But what�۪s most impressive is how the SL sounds. With a single channel amp, set clean, you could rely solely on this pedal as the drive channel. Totally sweet and awesome.
