In , The Ampeg Company, Inc. Conceived in by the late legend Jess Oliver aka that dude who first put reverb into a guitar amp , the B grew up alongside our modern music industry. Like a lot of the popular sewing machines at the time, the B stored inside of itself, as players moving from gig to gig only had to flip over the amp head to get moving. Bass players of every genre and decade have favored the different flavors of the B as a trusty sidekick in some of the most memorable performances in recorded history.
Motown fixture and demigod James Jamerson used a B for all of his live performances as well as the majority of his non-Motown sessions in Los Angeles. Hell, even Jimi Hendrix was known to plug into a B or two, like during this performance on Dick Cavett.
I’ve seen the info for decoding the post serial numbers but it doesn’t seem to apply to the serial number on the used BA I recently.
Louis Music era were all made after The amps made since have a digit serial number which is encoded for model, country, date, and year. The E is what? A variation on Europe? And is this an April model? Any pointers gratefully received. Therefore the serial number doesn’t fit the theory on serial numbers as it doesn’t list a country of manufactor as the fourth digit so I wonder if it’s pre or how I can guess the age.
Any ideas anyone? I tried searching for serial numbers for you to no avail. Have you tried emailing Ampeg?

It is in very nice condition. There are a few dings here and there, but over all and considering it’s age, I would rate it 7.

Read the current issue of VG. This unusual amp — which we might want to call the Jet-Reverb — is owned by VG reader Mac Lore, who came by it in the sort of lucky find of which dreams are made. To get it running right, Lore first took it to an amp tech who pulled all the original red and white Astron signal capacitors in the main chassis other than the one connected to the Tone control and replaced them with Sprague orange drops, a common over-reach of vintage tube-amp maintenance at the time.
Oh well, he got it working. The original resistors and capacitors do exist in the reverb sub-chassis, however, other than two large filter caps that were added by a second tech to replace the dried-out originals. It has the look of something thrown together on the workbench, perhaps to test a new circuit. In , a second tech who worked on the amp for Lore, Geoff Brumbaugh, drew a schematic of the reverb sub-chassis while he had the amp in his shop.
At this point, Lore was figuring his find might be an amp that was modded by an Ampeg factory worker for their own use. Having sought out noted Ampeg collector Ray Pirotta to field further information, though, he was put straight through to the font of all knowledge on this subject — to learn that this was a far more significant creation. He sent me a letter stating this, but it was later destroyed in the flooding from Hurricane Irene on August, — I had 40 inches of water on my first floor!
