Classic JCM with a bit more to it

The natural heir to the JCM800 dynasty with more versatility and bigger extremes. This thing can take you from something like John Scofield through ZZTop right up to the likes of Entombed or Slayer. Always with that trademark Marshall texture, which isn't for everyone, probably... but it sure as hell is for me.

Preferred Settings + Usage:

Setting with my old band was Presence at 8, Bass 10, Middel 4, Treble 6, Master Vol as needed but mostly 5, Gain at 18, Preamp 7 with a TS9 in front of it (and the occasional HM2). But currently I'm experimenting a lot with softer tones.
