Source Audio would sell a lot more of these if they did a tutorial for guitar players on how to program synthesizers. The C4 is an amazing synthesizer, but the default sounds are unremarkable and the sounds online aren't very musical. Were it not for the bass player who did a decent demo on programming, I would have sold my C4. Now I hold onto hope that I can learn to program well enough to craft some good sounds--because they are definitely in there.

Source Audio makes innovative and versatile pedals. The old version of Neuro was clunky but effective. The new Neuro is still really rough. The GUI is harder to use, helpful graphics are missing, resolution of displayed values lost precision, there are quite a few other issues that remain unresolved. I miss the old Neuro.

Introducing Pathways Reverb & Tremolo.
Pathways brings tremolo and reverb together in one compact pedal designed to feel great the moment you plug in. From spring reverb twang and classic amp tremolo to wider, more spacious textures, Pathways delivers sounds players reach for again and again - organic, musical, and easy to dial in.
Separate Reverb and Tremolo/Tap footswitches keep the two effects flexible and independent, while stereo operation, presets, and MIDI control allow Pathways to grow with modern pedalboard setups.

What's new:
Introducing completely refreshed Collider Editor. It's cleaner, easier to navigate, and built to make preset creation more fun and inspiring than ever.

Plus, instant effect swapping, routing options, effect icons, and a central Tap Tempo make the experience more intuitive. And of course, with SoundCheck™ you can explore and create presets in real time, without even plugging in a guitar, bass, or keyboard.
