Unholy Confessions amp settings — Boss Katana Air
The Avenged Sevenfold guitar tone for “Unholy Confessions”, dialed in for a Boss Katana Air with a Ibanez GIO GRG170DX. Studio version, Waking the Fallen (2003)
Gibson Les Paul Custom (bridge humbucker) → MXR MC401 Boost/Line Driver → Bogner Uberschall 120W head
| Knob | Setting (0–10) |
|---|---|
| Gain | 7 |
| Bass | 5 |
| Mid | 4 |
| Treble | 7 |
| Presence | 6 |
| Reverb | 0 |
| Master | 5 |
01NUX MG-101 (Boost/OD block)
Use the Tube Screamer or clean boost model to replicate the MXR MC401's tightening effect—low drive, high level pushes the amp's front end for added clarity and punch on palm-mutes
02NUX MG-101 (Noise Gate block)
Essential for clean stops between galloping riffs—metalcore demands tight gating
The Katana Air's Brown channel emulates a hot-rodded Marshall, which is brighter and more mid-forward than the Uberschall's scooped modern voicing. I dropped mids to 4 (vs original's ~5) and pushed treble to 7 to compensate for the Katana's smaller speaker rolling off highs. Your GIO's Infinity R pickups are moderate-output humbuckers—slightly hotter than a stock Les Paul—so gain stays at 7 rather than pushing higher. The NUX boost replicates the MC401's role: tightening low-end and adding pick attack.
