01Tube Screamer (TS9 or clone)
RECOMMENDED — not currently owned. Essential for tightening low-end and adding pick attack clarity. Run into amp's dirty channel. This was standard practice for thrash recordings at Morrisound.
Your JCM800 2203 is the exact platform this tone was built on — you have the right amp. The 2203 naturally delivers the tight, aggressive midrange bark heard on Tortured Existence. Without a Tube Screamer in front, your low-end will be slightly looser and the pick attack less defined; compensate by keeping bass at 5 rather than higher and pushing presence to 6 for articulation. Master volume at 6 engages power tube saturation for that compressed thrash punch.
