[sdiy] Re: CV wah-wah with gyrator <- with corrected link

One quick point...

the two opamp voltage followers could probably
be combined into one... both are 9V right ???

Add some small series resistance after the opamp and
then a large capaciotr to ground for decoupling.

The resistor in series with the LED seems improbably
high. Almost a bet that it will not work with the
next vactrol you try.

I'd look at better ways to control the LED...
look at some Buchla examples... The Lowpass filter /
gate is a good example.  The Mutron III envelope
filter is another.
