A four-voiced synth pedal for your guitar or bass.
The C4 Synth unites all the sound creation tools of a classic Eurorack modular synthesizer and packages them in a compact and easy-to-use pedal.
Out of the box, the C4 features six dynamic synth effects, with unprecedented tracking abilities, and lightning-fast response.
For those looking beyond the six onboard effects, the Neuro Desktop Editor and Neuro Mobile App offer a diverse library of presets.
Creating custom presets is super easy.
The C4 connects to the Neuro Editor via the pedal's mini USB port or the Neuro Mobile App via the phone's headphone jack and Input 2 on the pedal.
Once connected, you can easily browse presets on the pedal for testing.
Favorite presets can be saved with a single click to any of the pedal's 6 toggle switch positions (or 128 MIDI accessible positions).
