Quite the powerful and versatile pedal. The picture is stock but mine is like new but with velcro on the bottom. Comes with the Boss power supply. These sell new for almost $500 and used at $275 and up. You can find info here:https://www.sweetwater.com/store/detail/MS3Switcher--boss-ms-3-multi-effects-switcher.
I would be interested in a trade for a compact multi-effects pedal but not necessarily with amp modeling. A trade would need to be comparable priced or trade plus cash on your end.
