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.

The layout of the pedal is straight forward. 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 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.

The 6-band EQ uses faders for precision control. The bass Low shelf is +/- 13dB at 80Hz, 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 a player with maximum versatility. Traditional ¼” input and outputs are complimented by and 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 utilizing the desktop version of the Darkglass Suite of available Impulses Responses or custom / third party impulses, and a 9V DC adapter input. A ground lift and Cab Sim round out the feature of the unit.

"This marks our entry into new sonic territories, in our search to connect with jazz and clean-tone bass players on a deeper level,” says Marcos Barilatti, Managing Director of Darkglass Electronics. “With the Luminal Booster Ultra, we've created the ultimate tool for bass players across all genres, delivering precision, versatility, and unmatched tonal control.”

Street Price is $499

In the impetuousness of my youth, I was, among other things, a reactionary chorus hater. Such were the obligations of a lad that preferred the Pebblescompilations to the Police in the 1980s. So, upon my regular visits to the old Starving Musician on El Camino Real in Santa Clara, I would often peer at a cheap, used Boss CE-1 and think, “Damn ... looks cool. Wish it wasn’t a chorus.”

The Smashing Pumpkins frontman balances a busy creative life working as a wrestling producer, café/tea company owner, and a collaborator on his forward-thinking, far-reaching line of signature guitars. Decades into his career, Corgan continues to evolve his songcraft and guitar sound for the modern era on the band’s latest, Aghori Mhori Mei.

“Form follows function,” explains Billy Corgan when asked about the evolution of his songwriting. These three words seem to serve as his creative dictum. “Early Pumpkins was more about playing in clubs and effecting a response from the live audience, because that’s where we could get attention."
