The EBS MicroBass 3 is a powerful all-in-one analog bass preamp and DI pedal designed to give bassists complete control over their tone in any performance situation. Featuring fully independent Clean and Drive channels, the pedal allows players to run channels in series or parallel for everything from pristine studio clarity to rich overdrive and blended tones. Built using technology derived from EBS flagship amplifiers, it delivers professional-level sound shaping in a compact pedalboard format.

An onboard compressor, 3-band EQ with sweepable mids, and character filters provide extensive tone sculpting, while the flexible drive section offers multiple gain structures and voicing options to dial in subtle grit or aggressive bass overdrive. With dual balanced XLR outputs, the MicroBass 3 can send separate signals to front-of-house, power amps, or recording interfaces, making it ideal as a DI box, pedalboard hub, or standalone bass preamp.

Additional features like a built-in tuner, stereo effects loop, headphone output, and auxiliary input make the MicroBass 3 a complete bass workstation for stage, studio, and practice. Whether used to replace an amp on fly dates, shape your core tone on a pedalboard, or run direct into a mixing console, the EBS MicroBass 3 ensures consistent, professional bass tone wherever you play.
