The iconic bass amp sound of the ’60s and ’70s, exclusively for UAD-2 and Apollo.

Apollo interfaces.Track and reamp with legendary all-tube, B-15 tone — from jazzy clean to warm overdrive to heavy distortion

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.

As a former owner of a B-15 I was pleasently surprised with how well made this emulation really is. As it's a relatively simple amp, it's characteristics is really specific and UA nailed it. And as it's a very specific tone that I missed over the years and now I'm super happy to have it in my arsenal.

Next best thing to a real B-15
I can't afford the $2,500 for a real vintage B-15N, but after using UAD's version on many of my recordings, I'm super pleased with the results.

Great amp sim
This thing is nice ! Sounds fantastic and I use it way more than I thought I would . Don’t hesitate, just buy it . Another fantastic product from UAD .
H. Ruus
Unfortunately.... a bit disappointed
I have the Ampeg SVT plugin and thought this one would sound more old school with a swampy Motown sort of sound... but it doesn't. It's actually more trebly direct and not so soft
Definitely not what I was looking for.
All other plugins I have bought have been spot on and wonderful...
Wish I could trade this one for something elseV. Ferrera
Very good
To similar to the original!
J. Payne
Fabulous spongy bass tones
Tube amps give a certain sag and bounciness to bass that's hard to replicate, but this amp sim DOES IT. I'm a big P-bass + flats kinda guy, and for that sound, this amp just kills. I like the VR for bigger modern tones, but the B15N is something special.
As with all the UAD amp sims, make sure it's on a unison preamp spot, it actually makes the sim feel real.J. Sutherland
Fat Bass Tone
Really love the way this sounds. Nice bass tone that sits great in the mix.

THE Bass Amp for Studio Sessions
Fender Precision Bass + Flatwounds + this plug-in gives you all the Motown mojo. Absolutely clinical application for studio sessions. I have a p bass with rounds, a p bass with flats, and all you need is this + your favorite pedals for grit. Outstanding.

The sound I was looking for.
The Ampeg B-15N helps me to get that characteristic growl from my P bass. It's very easy to get good sounds from this plug-in.
