Ibanez TS9DX Turbo Tube Screamer. Made in Japan.
 
A more versatile version of the classic TS9!
 
Hot, +, Turbo and TS9
These are the 4 modes that are available on the TS9DX. While the TS9 offers up the classic overdrive and boost sound you know the original circuit for Hot, + and Turbo mode push your amp even harder. In + mode you get the same tone and response as the TS9 setting just with a bit more grit to push your amp that bit harder. Hot mode introduces more saturation and a touch more gain again while the Turbo mode will really push your amp almost into a more fuzz like tone but still with the playability of a sweet overdrive.
