Something similar to OPFXS V-Zero Guitar Synth?

Looking for a pedal shematic similar to this synth pedal.

Specially the tone after 0:40 mark

Look over at Freppo's stuff at parasitstudio.se.

The resonant low pass filter being swept from 00:38 to 0:58 can be done with a dual OTA like the LM13700 or a few dual opamps. Eric Archer's DIY project is pretty simple and is resonant enough to give a bit of self-oscillation at max,

Thank you very much I will give it a try.

I developed that pedal and we are making a DIY version out of it based upon our DSP boards. Still working around it but here's the reference site.

Probably it will be available as a full kit to assembly and as a custom reprogrammable version too.
