Source Audio EQ2 Programmable Equalizer

The EQ2 Programmable Equalizer is the perfect companion for any musician looking to enhance or add flexibility to their tone.  The availability of the full audible frequency spectrum across 10 completely customizable bands means that EQ2 is the EQ pedal not just for guitar, but for any electrifiable instrument.  This allows you to move each of the 10 bands to any point on the frequency spectrum from 20 to 20,000Hz.  With +/- 18 dB of boost or cut on tap for each band, bandwidth adjustments up to 10 times more narrow, flexible routing and separate stereo curves, an optional noise gate and limiter, and a deep interactive editing software, plus some shelving and high-pass frequency options, EQ2 is the ultimate Swiss-army knife for your tone.

The Neuro's sleek and user-friendly interface includes detailed parametric editing capabilities (Q factor and frequency shifting) for all 10 frequency bands, two-channel stereo options, noise gate and limiter controls, as well as detailed external expression control. Neuro is available for free download at the App Store (iOS) and Google Play (Android), and available for Mac or Windows systems on our Editors & Firmware Page. We highly encourage all One Series pedal owners to experiment with the Neuro - the Source Audio Neuro Community is growing by the day, with users constantly creating exciting new pedal presets available for download.
