If you can live with the touchy settings and the hard to pin down gate knob, the slightly blues rock flavored Tech 21 American Woman has IMO the sound. It can go from mild grit to trashy distortion. Your fundamental comes through clear whilst mixed with a very fat and very grainy "tubes and speakers breaking up" underpinning that punches through. Disclaimer: It's not for weak combo amps. Through my Behringer it gave out an undefined snarl. Through my SWR, it sounded wonderful. I love it! Got it for $70 (used) @ GC. I also picked up a Whammy. Nothing more needs to be said about that.
