Having spent many hours (too many!) over the past three weeks of my GT6b ownership trying to get: 1) The Synths to track properly. 2) The Harmonist & Pitch Shifter to hold a note. 3) The Touch Wah to... Wah a bit more. 4) The Pedal Wah to not suck all the bass tone. As it feels like I am banging my head against a wall, I am wondering.... "What are other peoples experiences with the GT6b?"
