Ampeg® B-15N Bass Amplifier
-
The iconic bass amp sound of the ’60s and ’70s, exclusively for UAD-2 and Apollo.
The Ampeg B-15 bass amp defined the sound of recorded electric bass. From Motown sides with James Jamerson to classic Stax records with Donald “Duck” Dunn, this 30-watt, 1x15, all-tube brute oozes character — delivering a warm and fat fundamental note that laid the foundation for ’60s and ’70s rock, funk, and soul.
Developed by Brainworx, the Ampeg B-15N Bass Amplifier plug-in perfectly emulates the circuitry, tone stack, and iconic thump of Ampeg’s limited-edition Heritage B-15N bass amp — exclusively for UAD-2 hardware and
Apollo interfaces.Now You Can:
Track and reamp with legendary all-tube, B-15 tone — from jazzy clean to warm overdrive to heavy distortion
Harness two flavors of the iconic B-15 circuit — 1964 and 1966 — each with switchable bias controls for further tweaking
Hone your tone with the robust and meticulously emulated two-band Baxandall EQ
Audition 42 separate high-end recording chains, featuring four different cabinets and multiple classic microphones
Take A Listen
The Sound of Giants
The Ampeg B-15N Bass Amplifier plug-in flawlessly captures the original hardware’s dual 6L6-powered circuit as well as its simple, ultra-musical two-band Baxandall EQ. Simply use the Volume control to dial in rich, smoky tones, perfect for jazz and soul, or inch the Volume up for a fat guttural growl that teams with harmonics and character.
Two Channels, Tons of Tones
An evolution of the classic B-15 recipe, the B-15N sports two channels — 1964 and 1966 — each offering two flavors of iconic tones. The 1964 side gives you a 25-watt cathode biased circuit, whereas the 1966 input features a 30-watt, fixed bias circuit. Sonically, the 1964 side is spongier and breaks up earlier, while the 1966 input gives you a tad more headroom and midrange beef. Additionally, you can toggle between selectable bias modes, yielding even more tones and textures.
B-15N FX Rack
The B-15N plug-in provides additional control over your sound through the inclusion of the Brainworx FX Rack. It features a Noise Gate to control low-end buzz, switchable high-pass and low-pass filters to provide even more tonal options, and a Power Soak circuit that allows you to dial in as much overdrive as you want, without having to crank the output gain.
Unison™ Technology for Apollo Interfaces
Harnessing UA’s groundbreaking Unison technology, the Ampeg B-15N plug-in gives you the impedance, gain staging, and circuit behaviors that have contributed to making this iconic bass combo one of the most recorded bass amps in history.

I was planning to buy the Ampeg portaflex, and I probably will sometime in the future. But now i’m not in a hurry anymoore. This plugin is great! It puts the bass perfectly in the mix with all the beautiful tone, grit and dirt you can possible expect from a real tube amp. It just sounds Amazing!

offering the OX Box technology in a plugin would be kind of a big thing to people..
something about the way a tube rectifier supply reacts to loading....if Mesa/Boogie is going to be a snot about licencing plugins, then make Eleven with selectable power supply rectifiers, and just walk around them..E. Koch
Eleven
and make sure you have Brainworxs get you the B-15N power section here for Eleven...
it's the only tube rectifier driven 6L6 sectionE. Koch
Eleven
you get all the power amp sections from the Brianworxs plugs, get the acoustic feedback from Softube, and the cab and mic modeling from the UA OX box, and put it all under one GUI....Eleven.
E. Koch
Eleven
think of Eleven as a consolidated modular tube power amp/cab/mic/and adjustable acoustic feedback plugin,
( where guitars and pickups are already modular, and preamps are going that way.. );
a way to get rid of the soaked amp heat, and the electrical power consumption that entails.
Eleven would be a true "green plugin"E. Koch
Eleven
think about how much national electricity would be saved if Eleven had modeled power amp sections....then, not only could people use the Brainworx Plug preamps, but also people wouldn't be power soaking their real tube amps....
and maybe more tube amp manufacturers would make amps with separate standby and power switches for their amp's preamps...or just start offering real tube preamps..
synthesizers were modular from the beginning...i don't understand why guitar amplification would take so long.E. Koch
Eleven
Eleven would work with all the Brainworx amps, ( except mine here ) if it had a Power Amp Selector Section, ( by tube type, #, and power supply rectifier )....i guess packaging tube power amp sections with Softube's acoustic feedback and UA's OX response, would be the best thing....
that way people can pick their preamps..
if Eleven, ( like that ) had a digital pre gain control...then i could just run a 610B...
i wired a Jensen Balancing DI transformer into my Baritone guitar's electronics...
so my "guitar cable" is actually a balanced XLR mic cable...and so, with the addition of a digital gain, the 610B would drive it just fine.....if UA wants to do Eleven that way..E. Koch
I Just Noticed The OX Amp Top Box ( bye bye acoustic feedback )
So UA already has Cone Break-Up Down To A Science !!!
Great, but what if my amp is a plug in ??? and what if i want acoustic feedback also ???
maybe UA gets together with Softube on the Eleven Plugin ???
like i said, they already have the Acoustic Feedback plugin developedE. Koch
Just the one review on this is fine
the rest of my reviews here are on the " Eleven, for UAD 2 "
there are several characteristic speaker cone break-up types...but the all would equate to a type of compression or limiting..
there is the alnico break-up, ( a smooth whoofy type break up )
and the aggressive green back break up ( more crunchy sounding )
and then more common types of break up that are not so well characterized...
suffice to say, a cone break-up type selector switch, in that section, would cover the bases.E. Koch
i thought of a name for " the loud box "
Eleven ....
Softube already has the acoustic feedback processor developed, and the Speaker Cone Break-up Compressor would need to be a second independent processing stage..
so it makes sense to have the one knob, that goes to eleven, in the middle; with the feedback parameters on one side, and the break-up compressor parameters on the other.E. Koch
part five of my 5 star review.
maybe Brainworks and Softube could work together on an "acoustic feedback /cone break-up compressor"... it makes sense that it would be one unit...a sort of "LOUD BOX" that could be used on any guitar amp plugin..
E. Koch
part four of my 5 star review..
if the guys at Brainworxs get board, maybe they could develop a "UAD 2 guitar speaker break-up compressor", ( with different speaker break up characteristics), to place in the signal chain after all their great amplifiers..
E. Koch
part 3 of my 5 star review
the 8X10 cabs on this are working as well for me as any impulse response would...it's really an awesome amp, so thanks all..
i have no idea how cone break-up could be worked into an impulse response anyway, and maybe i can get that sort of effect with my compressor set up..E. Koch
Part Two of my 5 star review
i have never heard anyone mention the fact that cabinet impulse responses don't have cone break-up...but they don't..
i like the sound of overdriven power amps, and a little cone break-up...i have softube's acoustic feedback plugin, and i like that allot....i just wish there was a way to come out of the power soak into a cabinet plugin with a dynamic break up adjuster...
in real life, i could put a 2X12 loaded with two 15 watt celestion blue back alnico 12s on this wide open 30 watt B-15N and get cone barking compression on the peaks.E. Koch
my baritone guitar amp ( 6 string, 30-5/8" scale, low A )
dual 6l6 power section with a tube rectifier here, part recipe for one chunky monkey...
it's not super high gain or anything, but i run on the clean side of guitar tone and jump through rings of fire for the sustain and feedback vs gobs of gain ( which in a way accomplishes the same thing, but there is a difference to me )D. Montoya
Hells Yes!
Finally. Seriously great bass tone in the box, direct to records. Very inspiring tones and feel. My bass go to.
