Hey, I recently bought a Sunn Coliseum 300 and I was wondering if anyone knew how to tell the age of the amp and if it was pre-fender buyout.
The Serial is: K89106
It says it is made by Sunn Musical Equipment and on the Quality assuance label is has the Sunn logo with a trademark/rights reserved marking.
Is there anywhere else I can look to check the age?
Thanks
