Darkglass Luminal Booster Ultra Pedal

Booster, Compressor and EQ Pedal for Bass – with IR Loading and Flexible Signal Routing

Expanded Control Over Clean Bass Tone

The Luminal Booster Ultra is a bass pedal that combines compression, boost, and EQ in one unit. Building on the Darkglass Harmonic Booster, it adds parallel compression with adjustable frequency range and a blend control for mixing clean and compressed signals.

Built-in Compressor with Real-Time Monitoring

A gain reduction meter provides visual feedback of the compression level. The pedal features a low-pass filter for the compressed signal, as well as controls for compression amount, blend, level, character, and gain – offering precise shaping of the fundamental tone.

Flexible 6-Band EQ and IR Support

A 6-band graphic EQ allows fine-tuning across the frequency spectrum. The pedal also supports loading up to seven cabinet impulse responses (IRs) via USB-C and the Darkglass Suite. The balanced XLR output enables IR switching at the push of a button.

Connections and Functions

Equipped with input and output jacks for instrument signal, a balanced XLR output with ground lift, a stereo headphone output, an auxiliary input for backing tracks, and USB-C for computer connection.
