Thomas Gabriel Fischer

Thomas Gabriel Fischer is noted for using the Ibanez TS9 Tube Screamer overdrive pedal, as mentioned on Alchetron. While the information originates from Wikipedia, it's widely recognized among Hellhammer and Celtic Frost fans that his setup has consistently included the JCM 800 and the Ibanez TS9.

The pedalboard contained a Ibanez TS-Mini, a Boss OC-3 Super Octave Pedal, an Ibanez WD7JR Weeping Demon Junior wah, and a Korg PitchBlack Chromatic tuner.

Since the TS-Mini was released in 2015 this pedal was obviosly not a part of his old Hellhammer and Celtic Frost era pedalboard.

Sinc the TS-Mini is essentially a miniaturized TS-9 it's quite possible that the original Tube Screamer used by him in old albums was a TS-9.

Since the Ibanez Weeping Demon Junior was introduced in 1999 it's obviously wasn't a part of his original Hellhammer and Celtic Frost era pedalboard. He used some other wah pedal in his old albums.
