Darkglass Luminal Booster Ultra

Ultimate Versatility for Demanding Bassists!

The Darkglass Luminal Booster Ultra is the technical all-rounder that should be part of every modern bass setup. With its combination of Booster, Compressor, precise 6-Band EQ and integrated IR Loader, this pedal delivers exceptional flexibility for tone shaping. You get a rich, controlled bass sound that can be tailored precisely to your needs—whether in the studio or on stage.

Innovative Tone Shaping

Thanks to the Harmonic Booster, you get a punchy, assertive tone that sits perfectly in the band mix. Parallel compression provides a balanced signal, while the finely tunable EQ gives you precise control across all essential frequency bands.

Modern Signal Management

The Gain-Reduction Meter gives you direct visual control over compression amount. Via USB you can load up to seven user-defined impulse responses, offering additional sonic options and making the pedal a perfect tool for a wide range of styles.

Luminal Booster Ultra Modes

The Luminal Booster Ultra offers even more flexibility because you can change the order of the compression and harmonic booster engines by long-pressing the left footswitch. That way you can activate either the blue or the red mode.

Darkglass Suite

With the desktop version of the Darkglass Suite you can load one of the available impulse responses from the library or add your own impulses or ones from others to use with your pedal. You can also adjust the headphone volume.
