last week I was looking for a good od peddle.
I wanted the SD1 to mod it to a zakk wylde like od.
I've tried several things: SD1, BD2, OD2, OD3, DS1, Uber Metal, Double Muff, Ts9, Jack meistersinger... and the marshall Bluesbreacker because the little thing was in the shop.
I went out the guitar shop with the gray heavy metal little marshall thing.
I've been given the Boss OS2... I use it to distort the natural sound of my classic 50, because I can't sitch from OD to distort with my foot on the BB2.
To sum it up: The BB2 is exactly what I wanted. And better.
(the OD3 has a real great tone too as it preserves the natural sound of yer gettar)
