Just speaking about the cab itself, what is the best sounding type (usual caveats apply ie; personal taste, drivers, type of music, etc.)? What materials, construction techniques, dimensions, etc., seem to produce the best results? Avatar has a very reasonably priced 4x12...any downsides sonically to one of these? Is there a definite mojo to older Marshalls, or are the newer ones as good? Just trying to get a feel for what people like and don't like in a 4x12 since I'm getting close to buying one.
