Didn't know what to think when I read about this pedal, so cheap, but yet so much technology packed in a very small pedal.
After receiving my GP-5, I took it at rehearsel one day, sounded great right out of the box, many very usefull sounds are already programmed, did some tweaking after the rehearsel to make the sound a bit my own, now it's always in my roadcase as a possible backup, if something would go wrong with my main live rig, but I also use it for small practice sessions and at band rehearsels, sounds really great, a for that price It just can't be beat, I like it big time...
