I had a GT-8 that sounded really good but it had this problem that drove Me up the wall. No matter what I did to try and deal with it there was this ugly distortion on certian notes. Very pronounced too. I finally sold it and went back to analog only. How is the 10 in that respect?The Boss GT-10 is awesome. Best processor I have used to date. It can do so much stuff that it'll keep you busy for weeks just navigating through it. The ods are incredible, as are all of the effects. I especially like the choruses, delays, wahs, and synth sounds. There seems to be an incredible amount of processing power. So far, I love everything about it.
