I just bought this unit yesterday and I'm pretty impressed with the sound quality. I am wondering though how experienced users are taking advantage of the features of the XTL. How do you run the unit when used on stage? Before your bass amps preamp, or do you bypass and go right to the power amp? I was thinking that best way to take advantage of the unit with my GK 700/Neo may be to turn off the AMP models on all the presets. There is lot to experiment with and it is slightly overwhelming. The line6 forum seems to be filled with complaints about line6 so I thought I'd get more useful info from the TB community. Thx!
