B|Amp Mk2 Bass Amplifier – The ultimate working musician’s toolbox

In late 2015, Bergantino Audio Systems founder and head engineer Jim Bergantino launched the original B|Amp. This award-winning, ground-breaking and revolutionary bass amplifier broke the mold, winning a host of awards and accolades, not only from the industry, but from the bass playing community worldwide.

With the B|Amp Mk2, this updated model gives the modern bassist even more tools for their sonic armory. Time never stands still, so Jim has taken all the goodness from the original B|Amp design and brought it forward, not only updating its look with a gorgeous new OLED screen, but also adding new and powerful features in the process, based on players’ feedback and suggestions.

Perfect for the studio, rehearsing at home, recording or playing live, the highly-advanced B|Amp Mk2 is incredibly flexible and delivers maximum performance in a lightweight, compact, yet intuitive package. Truly a chameleon in the world of bass amplification, it is more than suitable for electric, electronic and amplified acoustic bass tones and works great in any genre of music.

Drive Me Wild

Want some soft-clip purr added to your fundamental tone?  How about searing distortion or gritty fuzz that sounds like a big tube amp is about to blow up?  With our Big Fat Tube (BFT) drive circuits, all of that is at your fingertips.  Also, don’t worry about losing your low end or foundational tone, we’ve made sure that will never happen. 

By adding a clean/dirty blend screen, YOU control how much drive you want mixed into your signal.  Don’t worry though, even at 100% full drive, people will know who the bass player is.

Overdrive adds harmonic texture to the circuit, extending the voicing of the B|Amp Mk2 closer to the tone of a tube amplifier. The Distortion 1 setting is voiced like a tube amplifier driven into clipping, while the Distortion 2 mode recreates a harder-hitting tone, reminiscent of some of the classic pedals we all love.

Any of the three distinct drive tones can be used globally or easily saved in the memory settings.


Compress Not Depress

The built-in proprietary Bergantino Variable Ratio Compressor (VRC™) was designed to take into consideration the compression needs of today’s bass players and simply take the mystique out of compression to give you a better tone. We know of no other off the shelf compressor available today which can do what the VRC can do and with such ease of use.

With most of the currently available compressors on the market, you have to settle for a fixed compression ratio which makes it difficult, if not impossible, to find the sweet spot between finger style and the more dynamic needs of such playing styles as popping and slapping. Choosing a ratio which evens out the dynamics and thickens the notes for finger style playing will not eliminate or curtail large transients that can be created by slap or pop styles. On the other hand, a compression ratio chosen for countering large dynamic swings will typically squash the dynamics and musicality of regular finger style playing.

Using Bergantino’s VRC, the compression ratio will change dynamically, essentially adjusting itself to the style and needs of your playing. Set up properly, it will give the player a nice, even and thick fingerstyle tone while attacking those large, over the top transients, all without even having to turn a knob!

In B|AMP Mk2, VRC now comes with two options: Parallel and Series. 

In Parallel mode, 50% of the signal passes through the compressor and then sums with the unaffected signal, adding a very pleasing sound and feel. With the Parallel compressor engaged, players can expect more of a note thickening that adds weight and smoothness to your tone.  Conversely, our Serial compressor takes 100% of your bass signal and passes it through.  This gives a more traditional compression of your bass tone allowing for a more affected sound, popular for many styles of playing.

Speaker Profiles

One of the many features that makes the B|Amp platform unique, is that it considers and includes the response of connected speaker cabinets as part of the amplification signal path. This is a completely new approach to bass amplification and is accomplished through Bergantino’s proprietary “Profile EQ System”.

No other bass amplifier on the market has the ability to manage speaker and the overall system performance like the B|Amp Mk2, while at the same time uphold the utmost fidelity we crave with all our designs. Our approach to bass amplification is to give you, the player a blank canvas to create your tone, rather than be forced into a manufacturers insistence on how you should sound.

As a long-time speaker designer, Jim is well aware of the lumpy frequency response of the average bass cabinet out there.  Many musicians try and use the simple EQ of an amplifier to correct their tone, whereas in fact what they are doing is actually trying to correct these anomalies to give a flatter response.

So, we decided to do something much more useful, by allowing you to mitigate issues by closer matching the amp with the cabinet(s). In order to achieve this flatness, the frequency response of a given speaker cabinet must be known. With a complex counteracting EQ curve, the various dips and peaks can then be applied to a signal.

When shipped from the factory, the amp is loaded with a general-purpose profile that should suit pretty much any standard cabinet design out there. But to make this really simple and effective, we have made extremely accurate measurements for most of our own cabinet designs and configurations and you can download these specific Profiles directly from the Bergantino website. Profiles are then easily loaded to the B|Amp Mk2 via the front USB port and a standard FAT32 thumb drive.

Power on Tap

Many brands sadly often rate their amps without real-world, verifiable figures. The B|Amp MK2 features a custom tuned, yet powerful amplifier module and will provide up to genuine 800 W RMS power depending on the speaker load.  At 8 Ω (for example a single small cab) B|Amp Mk2 will provide 350 W RMS, @ 4 Ω this is increased to 700 W RMS, while at a 2 or 2.67 Ω load the power output goes to 800 W RMS.

Speaker impedance of the connected cabinets can also be matched in the software, this allows for optimal power transfer and allows B|Amp Mk2 to function safely right down to a 2 Ω minimum load – that’s low for an amp this size!

Totall Recall

With the memory storing capability of the B|AMP Mk2, a complete tonal scene, including compression, effects and tone EQs (including bright adjustment), can be stored in either of the onboard memory locations for future recall.  This also can be useful when you have different instruments that require totally different settings to get the tone required. With the optional Bluetooth Wireless Footswitch kit, you can store three settings and select any of these at your feet – without any cables!

Multifunction EQ Tone and Filters

Gigging bassists realize that the room has the ultimate say in your bass tone.

The B|Amp Mk2 employs a quasi-parametric EQ that lets you hone in on any frequency in the band as well as adjust the Q width of that frequency.  This translates into being able to quickly and easily handle any issues that tough rooms throw at the player.

  • Bass: +/- 9 dB Variable from 40 Hz to 120 Hz
  • Lo-Mid: +/- 9 dB Variable from 150 Hz to 800 Hz
  • Hi-Mid: +/- 9 dB Variable from 800 Hz to 3 kHz
  • Treble: +/- 9 dB Variable from 3 kHz to 8 kHz
  • Bright switch:
    +3 dB to +12 dB in 1 dB increments
    or variable from 2 kHz to 10 kHz in 500 Hz increments
  • High-Pass Filter (VHPF):
    Adjustable from 30 Hz to 100 Hz in 2 Hz increments

How about those annoying frequencies that ring out and feedback, especially with upright basses?  With its Variable Feedback Filter, B|Amp Mk2 lets you find and hone in on that note to attenuate it accordingly.

  • Feedback filter:
    Adjustable from off to -6 dB to -12 dB in 1 dB increments
    Frequency/note range from E1 (41 Hz) to G3 (196 Hz) in half step increments

Tune all the way down

This is where you can load up the custom speaker cabinet profiles (using a regular FAT 32 thumb drive), upgrade the software when we bring new upgrades to the platform or connect it to the (optional) B|Amp Bluetooth Wireless Footswitch kit for external control. This allows you to engage/disengage the amp’s Mem1, Mem2, Mem3 and Mute functions remotely with the quick push of a footswitch – all without any wires!

Helpful Connectivity Features

B|Amp features a myriad of connectivity options to suit many situations.

Dual Speakon outputs allow you to hook up multiple cabinets without daisy chaining.

The built-in studio-quality XLR Direct Output is software selectable Pre or Post EQ. This is ideal for recording in the studio or just for giving the house PA a suitably balanced line signal to work with. In addition, the secondary Line Output gives another option if you need an additional Pre-amp output.

For adventurous and creative musicians, effects can add a lot to your sound. With the B|Amp’s effects send and return loop, you can insert these effects directly after the preamp for more artistic tonal options.

The 3.5mm/1/8th” Auxiliary input, with independent gain control, allows you to hook in your phone, computer or an MP3 player for playing along with recorded music or another line level signal, like synths or drum machines for example.

As the B|Amp Mk2 can actually be safely run without a speaker load, the headphone jack provides a useful personal monitoring and practice solution. This makes it perfect for your late-night practice sessions, recording or when you just don’t want to disturb the neighbors!

Again, all of these features are designed to give you a blank slate to create, craft and evolve your tone with an amp that never goes out of style!

“From the moment I auditioned the Bergantino gear, the accuracy, articulation and detail from their amps and cabs was nothing short of breathtaking. Jim Bergantino is also a genius! He’s clearly a mind reader too, because within my Bergantino B|Amp is every desired feature I would’ve chosen if I was designing the amp myself, plus when connected with my HDN-112 & HDN-210 cabinets, the immediacy, clarity, richness and definition of sound is absolutely exceptional. Congratulations Jim, you did it!”
