TB is mostly about all things Fender. Ampeg pushed it's way in by the sheer might of its products. Acoustic Control Corporation is a phomenon of the 70's and was resurrected two or three times that I know of.Hey, serious question here speaking of the 70s...I love the SVT tone and completely understand why it's in the pantheon of holy grail bass tones among several other amps throughout the decades, but in 20 years around talkbass I've never seen the Acoustic 360 amps get near as much attention or acclaim. I do remember an attempted comeback a while ago...
Recently there were two popular resurrections. The first I know of was by Guitar Center, a series of MDF cabinets with heads that somewhat resembled the heads of the 70's with modern touches. They had one for a while I liked-- it had a 110 cab with a folded horn design-- I've always loved Acoustic's folded horn cabs. This model was more of a commodity that attracted the kids that could afford it. They've recently tried to upgrade their products but are still Acoustics in name only and made somewhere in some Asian country.
The second well known iteration is Acoustic Amplification, an American company that attempted to capture the magic of the original Acoustic Control Corporation but I can't say either way as I've never even seen one in person. I understand a few recording artist bass players played them but the amps never achieved success.
Some guys like @Jeff Scott @Passinwind @agedhorse or my other buddies at the GOF thread could correct what I mis-stated.
None of this has anything to do with why Acoustic isn't popular on TB. I've seen a lot of love for the original but not a lot of posts.
Here's the latest link to the latest attempt for the Acoustic Amplification:

For all I know, this could even be the cheap Chinese knockoff, I don't know.
