Markbass Pro Bass Mixer

A Markbass "pro tool" designed for multi-instrument setups

The Pro Bass Mixer follows the Markbass philosophy: offering a compact format, designed for the stage, with immediate usability. Here, there is no classic "color" effect, but a true floor-based control center, made for musicians who switch between multiple instruments and want to maintain consistent levels and controlled sound from one channel to another.

Who is the Pro Bass Mixer for, and in what contexts does it make a difference?

This pedal-format mixer is aimed at both bassists and multi-instrumentalists: double bass on stage, fretted + fretless bass, bass + baritone guitar, or even double bass with a condenser mic. Live, it simplifies the pedalboard by avoiding cable changes and securing levels. In the studio, it becomes a practical tool to compare sources, route to two destinations, or prepare a clean and consistent DI chain.

Controls, routing, and connectivity: everything to manage a complex setup

Each channel has Gain (to adjust input level) and Volume (to balance outputs), allowing smooth transitions from passive to active instruments without surprises. The two dedicated filters enable quick tone shaping: Hifizer provides a "modern" curve typical of slap/plectrum style (scooped mids, emphasized lows and highs), while Old School acts as a low-pass filter to soften the high end and restore a warmer, vintage roundness.

The key feature is output management: via a per-channel selector, you choose the send to Output 1 or Output 2. This allows dedicating an amp to an instrument, maintaining a constant feed to the console, or splitting two rigs (for example: a cleaner amp on one side, a more colored rig on the other). Two LINK inputs also allow chaining multiple units to expand channel count and build a custom configuration.

Sound

The Markbass Pro Bass Mixer favors a clean, clear, and effective approach: it emphasizes level management and tone optimization without complexity. The Hifizer filter delivers a more "hi-fi" and percussive sound, particularly flattering for pick attacks, funky parts, and lines that need to stand out in a dense mix. Conversely, Old School rounds off the highs for a softer, thicker sound reminiscent of vintage settings, fitting easily into rock, blues, soul, or reggae contexts. The gain reserve and precise controls help maintain comfortable dynamics and smooth transitions between multiple instruments.
