Darkglass Electronics: Luminal Booster Ultra
Darkglass introduces the Luminal Booster Ultra for bass guitar. The Luminal Booster Ultra combines the rich tone of Darkglass’ Harmonic Booster with the unmatched control of an adjustable frequency range parallel compression, 6-band EQ, gain reduction meter, and the choice to load seven custom Impulse Responses via USB.
“With the Luminal Booster Ultra, we've created the ultimate tool for bass players across all genres, delivering precision, versatility, and unmatched tonal control.”

Layout of the Luminal Booster Ultra
The layout of the pedal is straightforward. Across the top, from left to right, is an adjustable lowpass FILTER knob for the compressed signal, a COMP knob to adjust the amount of compression applied, a BLEND knob to blend between the clean and compressed signal, and a LEVEL knob to adjust the level of the compressor after the blend control. Added controls include a +/- 20dB BOOST, a CHARACTER control to allow selection between seven Impulse Responses, a MID GAIN +/- 20dB, and MID FREQUENCY from 250Hz to 2.5kHz.
Dialing in your tone with precision
The 6-band EQ uses faders for precision control. The bass low shelf is +/- 13dB at 80Hz, and the mid bands are +/- 13dB at 250Hz, 500Hz, 1.5kHz, and 3kHz. The treble is a high shelf of +/- 13dB at 5 kHz. The EQ is flanked by a MASTER fader of +/- 12dB to set the overall volume of the unit.
Input and outputs provide players with maximum versatility. Traditional ¼” input and outputs are complemented by a 3.5mm AUX IN for practicing with backing tracks via a smartphone or laptop, a stereo headphone out, a balanced XLR direct out, USB-C to connect to PC/Mac to utilize the desktop version of the Darkglass Suite for Impulse Responses or custom/third-party impulses, and a 9V DC adapter input. A ground lift and Cab Sim round out the features of the unit.
