Why these settings

The Blues Junior IV is a naturally bright, mid-scooped clean-to-crunch tube platform that physically lacks modern high-gain preamp saturation. To get as close as possible on the amp alone today, the 'FAT' boost is engaged with Gain pushed to 9 and mids pulled down to 3 to simulate Hetfield's classic Mesa graphic EQ scoop. A dedicated high-gain distortion pedal is strongly recommended to achieve the true percussive chug of the record; with that pedal, disengage the FAT switch and set amp Gain down to 2-3. Clean intro: pick lightly near the neck pickup with guitar volume rolled back to 6.

PRO TIPHetfield’s rhythm sound relies on aggressive, strictly down-picked strokes using heavy 1.0mm+ tortex picks striking close to the bridge saddles for instantaneous percussive attack.
