Not that you want a Warpig, but in my Explorer I have a Warpig/Mississippi Queen set. With a series/parallel push/pull pot for the warpig, I can get clean tones out of it and with the MQ it creates some outrageous sounds.
If you are really going for 70's with metal too, what about the Cold Sweat set? It is based on the John Sykes Thin Lizzy tones but TO gets some great Iron Maiden sounds from it.
