I have a Boss gt-10 multi effects pedal. It has only been used in doors, and for practice play. It's still in great condition, everything works as it would right out of the box, I've had this for about a year, and have only figured out 1/10th of everything you can do! Note: these go new for around $500, used, the cheapest I've found online was 340ish very used.Any questions, please contact me at 785-445-8154!
