This is the BOSS ME-90 multi-effects processor. I've barely used it. It has too many functions for an analog-loving old man like me. I've only turned it on two or three times, and of course, I haven't taken it outside. There's no doubt that it's an incredibly fun piece of equipment for someone who knows how to use it. Everything that came with it when I bought it, including the box, is included. Although not pictured, the batteries are also unused. I used my own adapter, so it's not included.
