Welcome To The Jungle amp settings — Marshall JCM900

The Guns N' Roses guitar tone for “Welcome To The Jungle”, dialed in for a Marshall JCM900 with a PRS Custom 24. Studio version, Appetite for Destruction (1987) — signature main riff and rhythm crunch

Why these settings

The JCM900's Channel B provides modern high gain directly, matching the extra cascaded preamp tube in Slash's S.I.R. Stock #36 Super Lead mod without requiring an overdrive pedal. Compared to Slash's low-output Alnico II humbuckers, the PRS Custom 24 pickups are hotter and tighter, so amp gain is kept at 7 to prevent unwanted compression while boosting mids to 7 to nail the Appetite roar. Leave your Maxon OD808 and Joyo preamp bypassed so the Marshall tubes carry the core tone.

PRO TIPDig in hard near the bridge with heavy pick attack to recreate Slash's aggressive bite; for the signature sweet-sounding neck solo sections, flip to the PRS neck pickup with the guitar tone knob rolled back to about 7.
