Along with the 2×10 speakers, over-sized transformers from Mercury Magnetics, and bias test points on the rear panel, this one also has Vibroverb style bias-modulated vibrato and Bassman/JTM 45 voicing for the normal channel and a PPIMV on the rear panel for getting dirt/grind/overdrive at reasonable volumes. This amp does both sparkling clean blackface reverb tones as well as crunchy sustained tweed/early Marshall overdrive. Too much fun! Stay tuned for some pro  demos soon!
