O.k., Bass Gods: I just picked up a ridiculously low-priced Mesa Powerhouse 1X15 cabinet from a local player who was rather eager to get rid of the equipment he purchased not six months ago. Now, in searching the databases, I have found some things that I would like to have clarified about this cabinet: 1. Are there people who use this as a stand-alone? How does it perform? 2. There seems to be some buzz about defective drivers in early production of the cabinet. Is this true? How can you tell if you have a cabinet that may be part of that defective group?
