My only reservation about the Wizzy M is for doubling. The original Wizzy E is my favorite cab for that, however the Wizzy M has a more Hi-Fi, transparent type of sound and doesn't have as much of the vintage warmth that I like with the Wizzy E for bass guitar. I'm hoping I get used to that, since I like the Wizzy M so well for double bass. It's really amazing for that.
