GHS lists a special set of their Boomers roundwounds as fitting the Ampeg AEB-1, but they don't normally stock them, and I'm not sure of the availability in recent years. They're actually alittle too long for a correct fit on an AEB-1, and they are very bright sounding.
The correct dimensions to fit these models are:
40 1/4" from the ball end to the end of the outer winding (the beginning of the silk threads).
45" in overall length.
I've had strings made up to these dimensions by four manufacturers so far: D'Addario, LaBella, Thomastik-Infeld, and Rotosound. Right now, all I have in stock are D'Addario Chromes flatwounds, and D'Addario XL roundwounds.
Some of my AEB-2's and AUB-2's were shipped with LaBella 760FL flatwounds, which I really like, butunfortunately I can no longer supply them. LaBella has been completely uncooperative and unreliablein filling orders, and I've given up dealing with them out of frustration. It's a shame, becausethey make a great product...
D'Addario is a wonderful company to deal with, and I like the Chromes flatwounds. They're somewhat tinny sounding when they're new, but after a few hours of playing, they soften up and have a nice warm tone. These are the standard strings on the new AEB-2 and AUB-2 Scroll Basses that I build, and I also think that they're the best choice for vintage Ampeg AEB-1, AUB-1, ASB-1 & AUSB-1 models.Some AEB-1 and ASB-1 owners may prefer the XL roundwounds, but I personally think that they are too bright for those instruments. The Ampeg "mystery" pickup has an annoying ring in the higher frequency range, and the roundwounds just make it worse. Like my new Scroll basses, vintage Ampegs were designed for the frequency curve of flatwounds, and putting roundwounds on one won't make it sound like an Alembic!
Early in the AEB-2/AUB-2 project, I had some strings made up by Rotosound. Although I love the sound of Rotosounds on the two Rickenbackers that I own, they were too bright and metallic sounding on my Scroll Basses. Some vintage Ampeg owners liked them, but I've now run out, andprobably won't be ordering any more.
Thomastik-Infeld made up a few sets of their flatwounds for me, and I like them. They have a different character than the other strings; much more flexible and springy feeling, with a very strong fundamental tone. Unfortunately, I don't have any more of them in Ampeg Length, and can't justify the cost of the minimum order to stock them.
I'd like to carry more brands and gauges, but there's a big initial investment required,and this is a very small market. I have to order 50-100 sets at a time and, with the setup charges, that costs me $800 to $2000. In a typical year, I only sell 30 to 50 sets total, so I can't afford to buy and stock a variety of types. I've chosen the D'Addario Chromes in medium gauge asa good string that most of my customers like, but that's all I can do for now.

My recommendations are D'Addario Chromes flatwounds, which are available in several gauges, or LaBella 760FL (light gauge) or 760FM (medium gauge) flatwounds. These are smooth, tight strings that have a wonderful warm tone. An alternative is Thomastiks, which springier feeling with a clearer tone. Roundwounds also sound good on an AMB-1, if you like the brighter tone.
I don't stock any of these strings, but a great place to get them is JustStrings.com. Remember, the AMB/AMUB is only 34" scale length, but you must have Super Long Scale or Long Scale Plus length strings.
