Popular Chinese clone of the Ibanez TS9/TS808 Tubescreamers. Can be switched between the two. Also has an internal switch, allowing the circuit to be adjusted for something representing a Kelley modded unit, or the original Ibanez configuration. Hardly used, purchased to get back into a band that never happened. Apparently this is an original run unit - they have since removed the Ibanez trademarks from the screen printing 😂
