Knockin' On Heaven's Door amp settings — Valeton GP-100

The Guns N' Roses guitar tone for “Knockin' On Heaven's Door”, dialed in for a Valeton GP-100 with a Gibson Les paul. Studio version, Use Your Illusion II (1991) — main distorted rhythm/riff tone

Original rig

Marshall Silver Jubilee 2555 100W Head, 1959 Gibson Korina Flying V with original PAF humbuckers, subtle delay pedal

Warm, singing mid-forward crunch with smooth sustain and classic rock bite — not modern high-gain, but saturated enough for sustain on held notes

Why these settings

The GP-100's UK 2555 or Jubilee model nails this tone directly — it's modeled on Slash's exact amp. Your Les Paul humbuckers are hotter than the vintage PAFs on the original Korina V, so gain drops from 6.5 to 6 and presence from 6 to 5 to avoid fizz. Mid stays at 7 for that vocal singing quality.

PRO TIPRoll your guitar's tone knob to 8 rather than wide open — Slash's PAFs were darker than modern pickups, and this restores that rounded top-end that lets notes bloom rather than bite.
