Effect Circuits?

I'm looking for some various effect circuits to play with and possibly wing up adding
to my audio system. Things like 2nd harmonic generators, sterio width controllers, etc.

Being in kit form or having a PC board available would be a nice plus.

Please list any you may have.

Thank you
 
If you want to play with stereo width in the digital domain before your dac, you might try Waves S1 plugin used in host program that can stream your audio in real time. https://www.waves.com/1lib/pdf/plugins/s1-stereo-imager.pdf

EDIT: Also, Waves Q10 digital EQ comes with a preset that can create artificial stereo even from mono sources. It divides the audio spectrum into narrow frequency bands, then pans every other band either hard left or hard right. The effect can sound fairly good on some material.

I've built a few guitar pedals - a fuzz with germanium transistors, an overdrive with a socketed opamp, and an envelope generator (MuTron clone)

The Fuzz was fairly easy. The OD was a bit harder but not too bad. And the Auto Wow was challenging. It worked for a while but then started cutting out. I need to open it back up and find the culprit.
 
Thanks all

I have a couple of the H2 boards (from the store).
I also have a Stereo Width Controler.

I'm considering an Expandor/Compressor.

A subharmonic Generator may also be interesting
for some older albums that had limited low end.

I have an comp/expander, Behringer Autocom, and I have never found using the expander to be useful at all for hifi. (I'm not sure having 60dB dynamic range from.a 40dB source is too smart.)

But...I have Behringer Exciter rack module, which IS really useful for processing music. Actually the bass processing is rather good.
