Source Audio SA249 One Series C4 Synth Pedal

On the surface, the C4 features a simple 4-knob interface and a choice of three guitar/bass synthesizer effects - just plug-in and submerge your instrument in a sea of swelling, buzzing, and swirling synth tones. If you want to take things to take things a bit further, we urge that you connect the C4 to our Neuro Desktop Editor (a free download for Mac and Windows) or Neuro Mobile App (a free download for iOS and Android).  Inside the Neuro Editors you will find the tools to personally create your own retro-futuristic synthesizer tones. Use the C4’s collection of four parallel voices, three oscillator wave shapes, ten-plus envelope followers, twenty-plus modulating filters, distortion, tremolo, pitch shifting, intelligent harmonization, programmable sequencing and more to dial in that perfect tone. Find it all, from the classic synth tones you've always wanted to replicate to those illusive abstracts you've imagined, but never actually heard. If you're short on time and/or patience, it's very easy to find tons of great sounds - simply  call up an effect from countless presets created by the Source Audio team or the growing legion of C4 users.
