1959 Les Paul Standard replica (Kris Derrig) + Seymour Duncan Alnico II Pro pickups into Marshall JCM800 / Silver Jubilee 2555 (clean/Roland JC-120 for verse cleans)

The Katana 50 MkII lacks a physical presence control so presence is omitted. Selecting the Brown amp type accurately recreates the cranked hot-rodded Marshall crunch, while pushing the midrange to 7 captures Slash's signature punch without becoming harsh on the single 12-inch speaker. Using the Les Paul neck pickup with the tone dialed back slightly delivers the vocal, fluty solo quality heard on the record.
