Bass Amped up… Now available in all major native formats!

Defining the sound of electric bass, the Ampeg B-15N has been instrumental in everything from Motown cuts with James Jamerson to classic Stax records with Donald “Duck” Dunn. The 30-Watt, 1X15 all-tube power machine is filled with character, giving you a thick fundamental note that has been responsible for huge records from the ’60s and ’70s - Rock, Funk, Soul, you name it!

Crafted by Brainworx, the Ampeg B-15N plugin emulates the circuitry, tone and iconic beefiness of Ampeg’s Heritage B-15N amp.

Instant Classic in the Box

Accurately capturing the original amp’s Dual 6L6-powered circuit along with a great sounding Baxandall EQ, the Ampeg B-15N Bass Amplifier could easily become your go-to bass amp. Using the best digital emulation technology, Brainworx recreates the world’s most recorded bass tone with ease. It really isn’t easy to find an amp that offers such a bold tone with the amount of detailed control to shape it. Only 250 Ampeg Heritage B-15Ns hardware units were built, all with the intention of replicating the classic sounds of the 1964 and 1966 models. The two channels — 1964 and 1966 — both deliver different styles of equally legendary tones.

The 1964 offers a 25-Watt cathode biased circuit, while the 1966 puts out a 30-Watt, fixed bias circuit. The timbre of the 1964 is a bit softer, while the 1966 input presents you with more headroom and midrange. You can also use the volume knob to define a thick and smoky tone, ideal for anything more subtle like Jazz and Soul, or you can crank it up to get a roaring growl that is rich with harmonics and grit. Of course, you also have the option of choosing between different bias modes, creating many more possibilities when it comes to your tone!

FX Rack That Rocks

The B-15N plugin offers further refinement of your sound with Brainworx’s signature FX Rack. Here you will find a Noise Gate that controls any kind of possible buzzing in the lows, selectable HP and LP filters which will allow you to further sculpt your bass tone. On top of that, you can play with the Power Soak circuit for further distortion avoiding over-boosting your output gain.

    My go-to studio amp is my Ampeg Heritage B-15N, so I’m very familiar with it. This plugin captures it beautifully. It’s a fantastic mix tool.
