Re: TC Electronics G-system or Digitech GSP1101 - thoughts?
I've found the G-System to be pretty transparent to be honest. I used a rocktron Xpression before, and that's mean to be one of the most transparent processors, and moving to the G-System did nothing but improve my sound.
Its a little complicated at first, but once you work out how the interface is set up, its easy. Its FAR easier than the fx options on the Xpression.
The only thing i dont like about it is the pedal loops. They add a little noise to the signal, too much for me so i dont use them. If you really want it with pedals loops, i'd suggest getting a loop switcher to do it for you (which is what i intend to do soon).
The build quality is excellent, and the ability to switch effects on and off on the fly is great (much easier than just using a midi controller in bank mode).
