SolidGoldFX Aurras Optical Vibraphase Phaser / Uni-Vibe Guitar Effect Pedal

The Aurras Optical Vibraphase by SolidGoldFX—a powerful effects pedal named after the goddess of sound, meets the legacy of its predecessor the Athena Vibraphase in a harmonious blend of legendary, vintage Uni-Vibe textures and innovative, modern prowess.

Rich, Energetic Soundscapes

Aurras Optical Vibraphase is a 2-stage asymmetric phase shifter built around a pair of selected and individually controlled opto-isolators—offering a clearer signal with minimal distortion while simultaneously isolating the audio path from any possible LFO interference.

The dual LFO setup, powered by a microprocessor, provides limitless sonic flexibility. Drawing inspiration from albums such as Band of Gypsys or the Dark Side of the Moon, the Aurras delivers the lush modulation and heavy pulse that have shaped Rock & Roll history.

Comprehensive Tone-Shaping Controls

With its dual LFOs, expression pedal input, adjustable dry mix control, and offset combined with Speed, Depth and Level knobs, Aurras transcends eras with a rich tapestry of intriguing, lush liquid soundscapes.

While the Aurras features a 100% analog audio path from input to output, it takes advantage of precise digital controls, offering soft-touch relay-based true bypass switching, on-board tap tempo and speed ramping.

Set your effect with the Speed knob, Expression Pedal, Tap Tempo, or by using the Ramp function. You can ramp up your LFO speed by simply holding the Tap Tempo footswitch, which will automatically ramp up to double your speed.

You can also ramp down your LFO speed by simply holding down the Bypass Footswitch. This will automatically decrease your speed to half. Repeat this process as many times as you’d like to achieve the desired speed.

Let’s talk about LFO Offset

Aurras runs on a pair of opto-isolators each operating on an independent LFO. While most Phaser or Modulation pedals use a single LFO to create their effect, independent LFOs can open a new array of effects by offsetting their symmetry.

The OFFSET ADJ knob and OFFSET MODE FREQ|PHASE knobs work in tandem. For a more conventional effect, turn the OFFSET ADJ mode fully counterclockwise, allowing both LFOs to be in sync with no offset. 

The FREQUENCY OFFSET adds rhythmic patterns by slowing down the second LFO, while the PHASE OFFSET fine-tunes the throb by introducing asymmetry between the LFOs.
