Re: Boss SD1 $30 shipped
As long as we're taking this thread and running away with it, I just plunked Christian's SD-1 on my board next to my Keeley Ultra DS-1. They are definitely different. The SD-1 is about mids and (at least Keeley's) DS-1 is more about lows and highs. You can hear that TS mid-hump thing in the SD-1 but it's a bit nastier that a TS, probably due to the asymmetrical clipping diodes.
It's worth having both a DS-1 and an SD-1 around, but if you have some other TS-style pedal maybe the SD is redundant. On the other hand, I LIKE the SD-1 and I never got on with the TS - they're similar, but different.
