Into a clean amp: Buzzy as crap. No dice.
Into a slightly dirty amp: Probably my favorite fuzz of all time. Texture changes tremendously with the volume knob. Doesn't clean up like a Fuzz Face, but you can go from light breakup to full-on fuzz territory and then some. The Attack knob never cleans the sound up, even at its minimum, but every position is very usable to my ears. Works well with single-coils and humbuckers, where I feel that my Fuzz Face tends to favor single-coils and fart out with humbuckers.
I'm sold, I have a feeling that this might kick a couple pedals off my board if the honeymoon lasts.
Been hunting for the fuzz tone in my head for a long, long time now, think this might be the one for me. Anyone else have a similar experience?
