Anybody have any knowledge of this bass amp?

It is not "an amp" or even a bass cab, It IS a 3-way PA speaker cab. The midrange horn is at the top.

 

And not a particularly inspiring PA cabinet at that, but considering the time and the intended market, it was about par for the era, maybe even a little better than average.

 

Depends on what you expect from it. I wouldn't plan on gigging it

 

It would make a great nightstand!

 

might be able to sell the super hip sunn logo on ebay for 25 bucks

 

Do you have a bass head to try with it? If you didn't wouldn't cost a cent to see if the old timer gets loud.

 

The existing 15 with the 2" coil has to go.

 

Boat anchor.

 

Those were a good working PA cab in their day. A big step up from columns (some with piezos, some without).

Used 'em 3 nights a week with a trio (vocals only). I recently tried to play my bass through them on a low volume gig--- by todays standards, they suck. My bass sounds better through a Line 6 studio 10 for low volume gigs..

 

Be a great monitor for a drummer. We used an old Peavey 1820 for that in a rehearsal space for the drummer, it worked pretty good.

 

At least they made good engine analyzers in the day....

 

Different spelling (Sun) and company. Not even close to being connected.

 

I'm pretty sure that's newer than '72 also. Sunn went to the white baffles, black grille and 2-color logo in the mid-late 70s - IIRC.

 

I hate to spoil the "made in '72" thing you have going on, but that PA cab was manufactured in the late 70's at the earliest, maybe even early 80's. Those were the waning days of the Hartzell ownership era, and the quality had really slipped. Now, in the classic era of '66 to about '74, Sunn issued some mighty and iconic bass rigs, and some formidable PA gear, but by the time that particular cab was made, they were on a par with Peavey. I'm looking at a 1972 Sunn catalog right now, and by that year their PA cabs were mostly shallow columns with multiple 10" or 12" speakers, but they would also pair their single 15" bass cabs(very hard to find)with a large throated high frequency horns. Anyway, good luck with your purchase, but don't expect too much from it as a bass cab.

 

Spend your $40 on a couple sets of strings.
Better than flushing it if you buy that cab.

 

The cab looks to me to be not as old as the early 70's. By appearance, it looks similar to my Sunn Beta Bass, purchased in the early 80's.

The woofer in that cab, also looks a lot like the original woofer in the cab when I bought it. After a fall in the back of my truck, I had to replace it as the magnet had shifted the voice coil during the fall.
I replaced it with a Gauss driver in the 80's. sorry for the sideways pic!
