PICKUPbridge TONE8 VOLUME10

Signal chain

01Boss SD-1 Super Overdrive

Used as a clean boost to push the amp into tighter saturation for the aggressive sections and solo — mimics BJA's BD-2 usage. Low drive, high level.

Level 7 · Tone 6 · Drive 3

02Boss NS-2 Noise Suppressor

Keeps the high-gain tone tight between palm-muted sections. Run guitar into NS-2 input, SD-1 in the NS-2 loop, NS-2 output to amp.

Threshold 4 · Decay 5

Why these settings

Your Les Paul Special's P-90s are the correct pickup type for this tone — no compensation needed there. The Blackstar's ISF cranked clockwise gives you the British mid-forward character of the Idiot Amp. Pushed mids to 7 (vs typical 5) because P-90s into a Plexi-style circuit define this record's snarl. Reverb at 0 — the album is bone dry.

PRO TIPAggressive downstroke-only picking on power chords is essential to the Letterbomb attack — BJA barely uses upstrokes on rhythm parts. Angle your pick slightly so the edge bites the strings for that spiky transient.
