I thought it had some promise, not as good as MP1 (and no where near as good as MP2 mmmm), but depending what you want, it's certainly better than 90% of the stuff that's out there as a stomp box. IMO it would sound much better with some Mullard long plates.. And they are silly IMO to ignore that, particularly specially selected low noise high gain tubes are one thing, but they all sound soooo different. Get on board guys.... hear the difference, it would probably sound almost reasonable with some Mullard long plates (but then that's what I like, and they do show up bad playing, so maybe a factor ??). Personally I think AD/A is going in the wrong direction, concentrating on stomp boxes and stuff for the old school plug into guitar amps. But hey it's their company, it's no secret I like MP1, and much much better MP2, good clean power amp stereo cabs, decent digital or analogue FX, floats my boat.. I was hoping for better, I'd like somethng new to replace my aging MP2's, seems that's not going to happen unless I do it myself.
