You can listen to my "music" it was all done with a GT-3 and I use it live as well...although it is not that great live in my opinion when used as a preamp...great as an effects processor minus the preamp if you're going through an amp's effect loop. I pretty much just use it for the synth sound when I play out and another dma for the main guitar sounds.
I love it for recording, practicing, as as an effects pedal (minus the preamp) when playing through a regular amp
