Facelift tone is THE AIC tone for me. Which, was either a slightly modded boosted 65 Bassman OR the Snorkler(Dude who owns the Snorkler said the Marshall was used for Leads, and cleans while the Bassman was the dirty Rhythm).....
But, if you can locate the We Die Young demo, Jerry used his Randall RG100es, and it sounds almost spot on to the record. Clearly it's how he dials it, and everything in his signal chain contributes.
