(Note: w/Marshall 1960AV V30-loaded 4×12)
Lead channel, deep and tone shi(f)t off.
Bass- 6, Mids- 8, Treble- 4, Presence- 2, Gain- 6, Master- 6.
No boost. Also note: this is loud. I found JJ pres and =C= EL34s to work well in this amp, though a pre full of JJs can get a bit murky; throw something else in the phase inverter.
