Cool VFD distortion module for Eurorack


It uses a vaccuum fluorescent display, which is actually a little tube (a triode I think?)

Seems to clip on the top of the waveform and fold on the bottom.

Similar to Korg’s NuTube:

Hopefully we can do supersampling in Audulus at some point and have more model-accurate overdrives. It’s tough to do it accurately at 44.1k.


And it also looks like it inverts the signal. I made a quick model, let me know how you think it sounds.

Very cool! Definitely beefs up that sine wave. Might make a kick based on this…
