Don't give up on the Fenders too quickly for blues.
The Bandcommander with xformer match turned down a little bit, output comp set to feedback mode, and a post cab block 5-band passive GEQ with a frowny curve, is a very dynamic responsive amp.
For me, even more than the crunch, I want miles of clean headroom, so that I get real nuanced, when I play the blues. That really sensitive dynamic feel is what I go for.
In front, one of many dirt pedals add some nice stuff too. Like the SDD preamp.
Cab choice with the bandcommander?
