This is an Ibanez TS9. A world-famous overdrive pedal loved by many musicians. It has a warm sound focused on the mids, and its unique stickiness is a major characteristic. When connected to the front end of a tube amp, you can get a soaring lead tone that makes the amp scream. The TS9 is one of the most popular TS models. Personally, I think it's the easiest to use among the TS series. It has that "THE TS" sound. The LED has been replaced with a blue one for better visibility. Velcro is attached to the back. I'm selling it because I've switched to a multi-effects unit.
