Description: GT-100 Multi-Effects Processor With the new GT-100 Version 2.0 update, BOSS' high-end multi-effects processor is now even more powerful than before, adding a host of great new features to its already formidable arsenal. Two new amp types are included, along with cutting-edge MDP effects, an acoustic guitar simulator, and an improved rotary effect. Just used it over a year. Used only at home purpose. just minor scars on the top. It's works fantastic and like a tank. Nashik Maharashtra
