Darkglass Electronics Luminal Booster Overview

Pure, Powerful, and Precise
Seamlessly blending the lavish tone of the Harmonic Booster with the versatile Multiband Compressor, the Luminal Booster Ultra from Darkglass Electronics offers up to ±20 dB of clean boost or cut for bass. With flexible 6-band EQ control on sliders, sweepable mids, and seven slots for cab sim IRs, this pedal is a tonal powerhouse.

The integrated multiband compressor features a dedicated footswitch and controls for Comp (compression ratio), Filter (adjustable low-pass filter), and Gain (makeup gain). The pedal sports a 7-LED gain reduction meter for keeping an eye on dynamics processing. The Character knob lets you tune your pedal for the perfect style of tone-shaping circuitry. I/O includes 1/4" input and output, a stereo 3.5mm aux input, a stereo 3.5mm headphone output (capable of driving down to 16-ohm headphones), and an XLR DI output for pro audio gear (like PAs and mixers), which carries your cab-sim-processed signals.

Cabinet Simulation
The integrated cab-sim IR loader features seven slots and can be manually added to the XLR DI output via a dedicated push button. The seven slots can be accessed by pushing the Character knob.

You can load custom IRs into the pedal through the convenient USB-C port and the Darkglass Suite app for macOS and PC. A ground-lift switch is also provided for breaking hum-inducing grounding loops while using the XLR output.

Sliders and EQ Control
The Luminal Booster Ultra features seven slider controls on the front, including:

  • Master for ±12 dB control over the total volume of the unit
  • Low-shelf control with ±12 dB at 80 Hz
  • ±12 dB adjustment at 250 Hz
  • Up to 12 dB boost or cut at 500 Hz
  • ±12 dB control at 1.5 kHz
  • Boost or attenuation of 12 dB at 3 kHz
  • High-shelf control of ±12 dB at 5 kHz
