01Boss GT-1000 T-SCREAM OD Block
Tightens low-end attack into the high-gain Mesa block
02Boss GT-1000 Noise Suppressor Block
Essential for stopping buzz between staccato machine-gun chugs
03Boss GT-1000 Graphic EQ Block
Post-amp V-curve: boost 80Hz/6.4kHz (+3dB), cut 750Hz-800Hz (-5dB) to replicate the Mesa 5-band EQ
Because the Player Strat's single-coil bridge pickup is lower output and naturally brighter than Hetfield's active EMG 81, the amp block gain is pushed up to 7 and the TS block provides essential tightness. The mid control is deeply scooped with an added Graphic EQ block to capture the iconic Justice V-curve. Clean intro: switch to JC-120 Clean block with chorus and neck pickup.
