SUNN Help me with the model

Pretty sure they made a beta bass with 1x12.

Or its had its baffle replaced.

 

$300 is IMHO, too much for an old solid state sunn with a 1x15 or 1x12 anyways.

 

I played one of those once- it was the definition of mud/rumble/indistinct/boom. Be glad dude isn't replying.

 

Sunn didn't make a 12" Beta Bass combo -- that is a Beta Bass 1x15. I owned one and worked in a store that sold Sunn ca. 1980. The enclosure was big, esp compared with today's combos, so there's a "margin" of a few inches around the driver, creating the illusion that it's smaller than 15". See also the Acoustic 126, a direct competitor of the day, which demonstrates the same phenomenon, only more pronounced. It looks like there's a 10" in there.

That's a $200-$225 amp tops if he's still got the footswitch. "Not too heavy either" is not too accurate.

 

Those old Sunn tube amps (100S, 200B, 1000 and 2000) were absolutely awesome amps. There were very few solid state anything made over 30 years ago that were any good.
