I've never enjoyed the distortion generated by the unit, though it takes a good distortion in any case to make me interested. This thing has been from Virginia to Saudi Arabia and back home to Maine. The ART is something that I'll definitely hold on to. It fits in well, travels lightly and does the job. If I had one thing to change about it, I would consider re-vamping some of the digital distortion settings.
None seem bluesy or rounded off enough, just shallow and biting.
I'd buy another at the same price. Seems like every time you switch to a different patch you have to mess with the thing for 10 minutes. The manual is average. The flanger is nice. To get a good distortion sound I have to use my boss overdrive pedal.
