Variable capacitor

R2 can go as low as U1 can comfortably drive without distorting, so probably not much less than 1k if you're using a TL07x. At the other end of the range, I probably wouldn't go over 5k to keep the noise low.

When choosing a P2 value, keep headroom in mind. 1+ P2/R2 is the U2 gain, and too much gain will cause clipping. So, basically, I don't think a P2/R2 ratio of much more than 10 is a good idea. P2=50k and R2 around 5k should work just fine.

I haven't built the physical circuit yet, but I see no reason that it shouldn't work exactly as it does in the simulator.

Not being a true engineer, I was surmising pretty much the same thing, but wanted to ask. Thanks!

I'm not a real engineer either. Best to try this on a bench or in a simulator, check for stability and so on.

I read somewhere that there's a floating version, but haven't investigated further.

There are a couple but they are all complex and component heavy to my knowledge.

Man I'm actually tempted to do another ssbs F*** overdrive with one of these. Theoretically you could dial in the strength of the sag effect
