Class-D - Massive Power, Perfect Sound

Thanks to our revolutionary Class-D amplifier technology, we are able to provide you with enormous power and incredible sonic performance in an easy-to-use, ultra-portable and lightweight package. Class-D amplification makes all the difference, offering the ultimate in energy efficiency and eliminating the need for heavy power supplies and massive heat sinks. This amazing technology makes it possible to design and build extremely-powerful products that are significantly lighter in weight than their traditional counterparts, while using less energy and protecting the environment.

MOSFET Preamp - High-Voltage, High-Headroom Tube Sound

BUGERA ’s revolutionary high-voltage MOSFET preamplifier redefines solid-state bass tone, providing the sound, feel and immense dynamics of an authentic tube amp. Like with real vacuum tubes, our new MOSFET design equally operates at high voltages, providing this preamp with unheard of headroom to honor all of your playing dynamics; from your subtly-nuanced signature riff s and bass lines, to your most powerful, attention-grabbing solos. The ULTRABASS BXD15A is all about tone, and this highly-versatile and responsive MOSFET preamp provides an abundance of headroom for consistently crystal-clear and faithful sound reproduction – no matter what style of music your gig calls for.

Studio-Quality Compressor - Stairway to Heaven

Our studio-grade compressor is based on classic and famous studio equipment from the 70’s. This totally transparent and musical compressor design allows your full dynamic range to shine through until your signal reaches the compression threshold, which is indicated by the highly visible status LED. The compressor increases sustain and gently smoothens out signal peaks, which is especially handy when you’re laying down the funk, à la slap and pop – or hammering home your most-aggressive metal lines. The resulting output level lets you unleash powerful and impact-laden bass lines, while still sitting right where you need to be in the mix!

DYNAMIZER Technology - The Secret Weapon

What is known as Parallel Compression or “New York” compression, is a dynamic range compression technique used as a secret weapon in high-end sound recording and mixing. Parallel compression is achieved by mixing an unprocessed “dry”, or lightly compressed, signal with a heavily compressed version of the same signal. Rather than bringing down the highest peaks for the purpose of dynamic gain reduction, it reduces the dynamic range by bringing up the softest sounds, adding audible detail. It is most often used on stereo percussion buses in recording and mixdown, on electric bass, and on vocals in recorded and live concert mixes.

Now this amazing technology is available to you! We have integrated parallel compression in our DYNAMIZER technology to provide you with tone and dynamics that are unheard of to date. By working directly with the amplifier, our DYNAMIZER technology adds incredible detail and powerful, fat punch, so your sound is always impeccable, whether you’re playing super-soft – or at the extreme volume levels that push a dB-meter to the max! DYNAMIZER allows you to take full advantage of every single Watt of your amplifier!

Sound Off

As bass players ourselves, we know that only the ultimate in tonal flexibility will do, so we designed the BXD15A to satisfy the most-demanding bassist – you! The passive Gyrator EQ circuit provides the sound and feel of traditional tube amps, while dedicated Bass, Mid and Treble controls, working in tandem with a sophisticated 5-position mid-frequency switch, helps you easily dial-in any tone you can imagine. And since we want a little extra sometimes, BXD15A’s Ultra Low and Ultra High switches are always there to launch your tone into the sonic stratosphere. A handy Mute switch allows you to tune up silently, and the -15 dB input switch enables you to jump between passive and active basses in a flash.

Get Connected

Equally adept in the studio, on the stage or in your practice room, the BXD15A is replete with convenient options and connectivity to help you get the job done. For recording and live performance applications, we’ve provided a world-class, balanced DI output. Also included is a dedicated FX Loop for connecting your external effects and a switchable Tuner Output that’s perfect for use with a tuner, or as a live monitor feed. An Aux input is provided for playing along with your favorite music, and the headphone output offers superb tone while practicing. We’ve even provided connectivity for our optional FSB102B footswitch, so you can remotely-control Mute and FX Loop functions.
