01Compressor Block (Boss GT-1000)
Used gently before amp block to add pick attack definition and sustain to single-coil pickups
02Graphic EQ Block (Boss GT-1000)
Post-amp block V-curve to replicate the Mesa 5-band graphic EQ essential to the Puppets tone
The Fender Jimi Hendrix Strat has lower output, brighter single-coil pickups compared to James Hetfield's high-output humbuckers, so the tone knob is rolled back slightly to 8 and pre-gain compression is engaged to thicken the attack. The GT-1000's BG LEAD amp model carries the core Mark IIC+ gain, while the post-amp Graphic EQ applies the iconic 750Hz V-curve cut to match the album's tight, scooped character. Keep the reverb completely off to preserve the dry, precise thrash rhythm punch.
