Start a various, this Showman came to me in a a home built 2x0 cab, and I realized that it would slip right into an empty Pro Sonic cab I bought. Voila! If he wants the Bandmaster cab, then the Bandmaster chassis Inhave will go into the Pro Sonic cab. If the Bandmaster chassis had not been much abused I old no sell the head cab...even though the cab and chassis are not original to each other. Someone actually gutted a BF Bandmaster chassis and built a solid state amp in it. They hogged out crude holes which I had to have repaired. My friend did a fantastic job of re-establishing the chassis metal and sockets. As for the Showman/Dual Showman thing, at that time there was no ‘Dual’ applied to the front panel. The OT model number tells one what one has. This one is a Dual Showman with the 4 ohm OT.
