Why these settings

Angus's tone comes from Marshall preamp saturation plus speaker cone saturation at extreme volume (10/10). The Blues Junior is a Fender platform — naturally scooped, treble-forward, and lacks Marshall mid-forward voicing. Compensated by pushing mid +1 from Angus's typical 5/10 setting, dropping treble -1 to counter Fender brightness, and setting gain to 7 to approximate preamp overdrive without pedals. Master volume at 8 pushes the power section into saturation territory; this amp will not achieve the Marshall roar at bedroom volume.

PRO TIPAngus gets his sustain from volume causing the speaker cone to lock up — hit the strings as hard as you physically can to force the amp to compress and fight back; pick attack intensity matters more than any knob setting on this tone.
