Practically brand new. I bought it a while back, but never really used it. I have a GT-6 that I still use. It's just been sitting in the jam room unused. Still in perfect new condition. Truth be told I hate setting up new gear, which is why I never switched over the GT-8
I may be able to find the manual, not 100% sure on that. I can download the pdf from BOSS though. I will include a CD with a couple of GT-8 editors and some patches I downloaded so it can be edited and tweaked as well as being able to load and save patches on a Windows machine.
Asking $350 shipped anywhere in the lower 48 states.
