Like all of their One Series pedals, there's a lot more to the Source Audio Mercury Flanger pedal than meets the eye. Right off the shelf, it offers three distinct flavors of flanger: smooth and subtle flanging, through-zero flanging, and highly resonant flanging. Where the magic happens is with Source Audio's Neuro Editor software, which takes you inside the pedal's powerful 56-bit Sigma DSP and allows you to fine-tune all sorts of parameters. Neuro also gives you access to more flanger engines, as well as phasers and choruses. And once you've created your ideal effects, you can save up to three of them on the Source Audio Mercury Flanger pedal for instant recall, without ever having to open the editor again.

True through-zero flanging
The original flanger effects were created by manipulating the speeds of two tape reels, and an interesting effect would be created when the two reels re-synced. This is referred to as through-zero flanging, and it's not an option usually found on flanger effects pedals — but you'll find it on the Mercury Flanger as one of the stock flanger types. As the cycle reaches its peak, you'll hear your sound collapse into itself. The other two stock flanger modes are a smooth and subtle Classic flanger and a highly resonant Shadow flanger.

Customize your tone with the Neuro Editor
You can make your Mercury Flanger pedal your does-it-all modulation effects box simply by using the free Neuro Editor. Connect the Mercury Flanger via USB to the Neuro Editor, and you'll have access to Source Audio’s free library of additional phaser, flanger, and chorus algorithms — each directly downloadable to the pedal. The Neuro App also offers an extended range of adjustable parameters that includes Feedback, Output Level, embeddable Tremolo, Parametric EQ, advanced signal routing, and much more.
