(Anyone know how to embed soundcloud code here?)

More info, schematic and vero layout can be found in my blog:

Dual layer PCB layout for fabrication is already done and PCB's will be sold later through my webshop

I hope you like it :)

Never thought about that you could not hook up a speaker and just use it as a vca. This ic has some potential  :) I have one on my breadboard all the time as a headphone amp.

Seen it used in a compressor before, but hadn't thought about a trem - nicely done Freppo.

Thanks! :)
Yes, it certainly has potential. I just love when I can avoid LDR's or transistor VCR's...
I kinda went alittle crazy and took every possible measure to avoid LFO ticking.
Even my vero layout is dead silent, so I think it was worth the extra trouble/components. :)
A more conventional tremolo would be even easier to do with less parts.
