The ST9 is the culmination of the Tubescreamer. The sound is similar to the TS9, but delivering more sustain and drive. It has two JRC4558D IC chips instead of one, as on the TS9. A fourth pot for Mid Boost is introduced to improve tonality control. Briefly available exclusively in Europe it is utterly rare.
