I know that a Blues Breaker is a 2x12 cabinet, but there are all kinds of 2x12 configurations. The Fender DeVille comes in a 2x12 configuration but they are diagonally set...is that still a blues breaker? The Peavey Heritage VTX is side by side 2x12...but it is slightly slanted back...is it still a blue breaker? Is a 2x12 cab with a separate amp still a blues breaker? Any other 2x12 configurations that could be considered blues breakers?
