BOSS MS-3 Multi Effects Switcher - A programmable switcher with multi-effects for guitar and bass from BOSS. I bought this for live performances, but I'm selling it because it didn't suit my preferences. It's almost new, but there might be a little bit of dirt. No issues, operation confirmed. I can send the tape on the bottom as is if you'd like. [Included Items] Dedicated power adapter, instruction manual, box Please understand that this is a used item before purchasing. Instant purchase is OK.
