Oh man, I had one of these when I was 18. I freaking LOVED it!! My buddy and I used the built in recorder to make a full 9 song album. It actually turned out really well. I never had a lot of cool gear when I was younger so when I got the GNX 3 I was in heaven. It's great for jamming in your room/using headphones like you said. However, there are way better things out there, I definitely wouldn't use it to gig though. Just hang on to it man, if you do sell it, you'll never come close to what you paid. Sorry dude, I just realized how old this thread was, oh well. Hope you still have it!!
