Master of puppets amp settings — Fender Blues Junior IV
The Metallica guitar tone for “Master of puppets”, dialed in for a Fender Blues Junior IV with a Thoman Fender Stratocaster. Studio version, Master of Puppets (1986) - Main rhythm riff
Mesa/Boogie Mark IIC+ slaved into Marshall JCM800 power amp, Jackson King V with Seymour Duncan Invader/EMG pickups, Aphex EQF-1 parametric EQ with graphic V-scoop
| Knob | Setting (0–10) |
|---|---|
| Gain | 9 |
| Bass | 7 |
| Mid | 3 |
| Treble | 7 |
| Reverb | 0 |
| Master | 4 |
The single-channel Blues Junior IV is a blues-oriented tube combo with high headroom and cannot natively deliver Mesa Mark IIC+ thrash saturation, so maxing Volume/gain with FAT boost engaged is necessary to get the closest playable bite. The mid control is dropped to 3 to emulate the classic Metallica graphic EQ V-scoop, while bridge single-coil treble is softened with the guitar tone knob at 8. Clean interlude: disengage the FAT switch and roll guitar volume back to 4.
