Recently played through a M. Boog cab w/ the Vintage 30s. I had thought this cab would be a go to for p.muted detuned stuff. However, it sounded absolutely horrible. Muddy, poor bass response, inarticulate, etc. Yesterday I played through another V30 in a line6/Bogner combo, and loved it. What's the deal? Blown speak? Incorrect cab wiring? Anybody have experience with bunk V30s?
