I'm a staunch Marshall guy -have been for ever, but yesterday I was in my friend's shop and there is a re-issue Super Reverb blackface (65?) so I tried it out. Wow. Waht a fat, warm sound outta those 4-10's. Tube rectifier too. So without a master volume how would I get a higher-gain sound? Throw my TS-808 in front? Add a master vol circuit? I really want to hear from the Fender amp pros here- I'm thinking if I can retain that fat, warm tone -but get it to produce a 'Marshally" gain like Derek Trucks gets it would be a perfect amp for me. Any thoughts?
