Own a Blues Junior, modded, with a C Rex speaker. While it is a nice speaker, I seem to have lost a ton of break up and drive...guts really. It's loud but too clean for me. Anyone try a Weber Signature 12 or 12s (alnico or ceramic)--any thoughts on which one does the gutsy, "tweed-like" breakup better? Or any other speaker suggestions in that light for the Blues Jr? Thanks for any help!
