The Ibanez TS9 Tube Screamer is a reissue that's just like the original in so many ways. Same factory, same components, same housing, same famous seasick-green paint, and the same crankin' overdrive that made the original one of the all-time classic pedals. Plug it in. Crank it up. You'll hear what all the fuss is about. Tone, drive, and level controls. The TS9 is powered by a 9V battery or optional (sold seperately) AC adapter.
