Fender 300 pro buries any tube amp for clean volume, has tone for days and with the blendable over drive channel has made my fuzz pedals obsolete! On the fender 810 it is glory personified.
Btw... the 215 cab, if it's the older tall one is your weak link in both volume and low end. If its the cab I'm thinking of, that design was low end deficient and farted out easily.
I think two of the newer Fender Pro Neo 1x15 cabs brings home the bacon with good clean tone. I agree, the old 2x15 cabs from the 1970's were poorly designed and couldn't handle much power. Just my opinion. I'm running a 1978 Fender Bassman 135 with two of the Pro Neo 1x15 cabs and it's clean all the way up to the highest volume I can stand.
