I've had an old VT brand cab for a while... it's nice and heavy. Pretty deep too. But I just bought an old Vox cab. Aesthetically, it's way cooler. All beat up, filled with mojo. I just bought a new amp head. I've noticed that there's a lot less bass response. I don't think it's in the head, but I've only got one set of speakers for the two cabinets. Can the cabinet construction have such a huge difference? Is there anything I can do to correct it?
