Yes. You are right about the EQ. It's very subtle, the buttons do make a big difference, but the controls are limited.
Luckily it sounds great when you plug straight in. I suppose a compact 100W BTA head would be my ideal amp... If they made one.
Maybe ashdown would like to make me a one off, just to test of course, probably over a 25 year period or until I pop me clogs... that would be helpful.
