Re: Talk to me about the Boss DS1 in stock form.
Vai, Lynch, and countless others have used a DS-1 as a boost pushing a crunchy Marshall, Satch used one as his main distortion into a clean channel. Of course, some of those may have been the older MIJ or early MIT versions with the Toshiba TA7136P chip. I know Vai used a Keeley SEM modded new version for a while too (pretty sure all the Keeley modded ones are the new ones). As mentioned, the original versions are quite a bit warmer sounding, I've tried one next to a newer one and there is quite a difference.
And before it gets asked, no, the new ones can't be modded to be like the old ones, it's a very different circuit.
