Float away with the liquid, swaying effects of this state-of-the-art stereo chorus pedal. The Gemini Chorus offers three types of deep, hypnotic chorus. Classic mode creates a single voiced effect that conjures subtle and creamy tones from the first wave of 1970s chorus pedals. The thick and rich Dual Chorus provides a smooth, yet animated double voiced effect. The lush and spacious Quad chorus recaptures that ‘80s vibe with its less than subtle rack system sound. Once you’ve found your chorus, dial in the sweet spot with the onboard Mix and Tone controls.

Out of the box, the Gemini offers tremendous tonal range, but beneath the hood resides a much deeper level of power and flexibility. Every pedal in the One Series line is compatible with the Neuro 3 Mobile App (a free download for iOS and Android). Link the Gemini to the Neuro 3 App and access Source Audio’s free library of additional phaser, flanger, and chorus algorithms – each can be downloaded directly to your Gemini Chorus. The Neuro 3 App also offers an extended set of adjustable parameters including Feedback, Output Level, embeddable Tremolo, a Parametric EQ, Advanced Signal Routing and more. Plus, every One Series pedal is fully MIDI compatible when coupled with the Neuro Hub (formerly Soundblox Hub), giving you the power to save up to 128 presets.

We are huge fans of Bill Vencil (a.k.a. "Chords of Orion"). Bill is Youtube's premier ambient guitar guru - he always finds beautiful, beautiful sounds, and he certainly found beauty in the Gemini Chorus.

Our man Brendan Mowat-Smith went full-on 80s is this fantastic Gemini Chorus demo video. There are some nice synth /Gemini clips in here as well - Everybody Wants to Rule the World!

Boston bassist, Jesse Williams worked with us on this gorgeous Source Audio produced Gemini Chorus demo video. Chorus and bass guitar are a fantastic and time-honored combination.

Spend some time with our friend Nick "Just Nick" Jaffe and the Gemini Chorus. Nick is a our favorite knob-twisting philosopher, so we highly recommend you listen to what he has to say (and play).

Job one in the development of the Source Audio One Series modulation pedals - the Gemini Chorus, Lunar Phaser, and Mercury Flanger – was to create three great sounding, flexible, and easy-to-use pedals. Out of the box, that’s exactly what they are – plug ‘em in, select from the three onboard flanger, phaser, or chorus engines and make beautiful music… simple. But there is much more here than meets the eye (and ear) - the truly “Big Idea” behind our One Series modulation pedals was to give musicians a second, far deeper, set of options and editing tools with which to craft the perfect tone. The Neuro 3 Mobile App is a free downloads for iOS and Android. Neuro 3 basically gives you access to the effects of all three pedals, so when you buy any one of the Lunar Phaser, Mercury Flanger or Gemini Chorus, you're essentially buying all three. The Neuro 3 Editors offer a huge collection of chorus, flanger, and phaser engines as well as an expanded set of editing parameters. After editing your preset, burn it directly to the pedal and access it without reconnecting the Neuro 3 App.

All of One Series pedals respond to MIDI messages (to varying degree - see below) from a Digital Audio Workstation (a.k.a. "DAW") via their mini type-B USB port. Email [email protected] if you have further questions.

  • Includes 1/8” to 1/4” cable for Neuro 3 Mobile App connection.
  • Power Consumption — 150mA
  • USB port — Connects to Mac or Windows PC for firmware updates and the forthcoming in-depth effects editing software.
