out of those three?I havn't tried the line6 distortion,but would throw any amount of money down,that the Boss mt-2 would give a way better sound.

I actually have a question to whomever can answer...ive ran an mt-2 through a solid state head,but was thinking what running one through the clean channel of a good tube amp would be like...Would the mt-2 completley 'take over' the sound(as it does on a solid-state clean channel) or would the amps tubes shine through at all?...I think that setup(MT-2 and a decent tube amp)would create a ballsy tone.
