How do these compare to other Princeton circuits? I have the opportunity to trade into a minty one. I wouldn't use any of the pull boost knobs etc. but from what I gather it's a higher headroom Princeton with a mid knob and presence. My questions; how is the master volume on this? I don't need tons of gain but how are the edge of break up tones? Can I get into tweed territory with the mid boost knob? I'd be giving up a Savage Macht 12x for it. Awesome amp but I'd like something with built in verb and some more EQ knobs would be nice. My main amp is a BadCat 30r so this would just be my grab and go. Thanks.
