Thanks, but as a couple of people pointed out, the author
of the page was using a font that displayed omega. I don't
have that font and saw "S"

As for the inductors, I found that relay coils are mostly in that
range of a few hundred mH. One small RS transformer had
two 600mH secondaries

Not sure how these will fare as audio inductors.The project is
making modifications to a Crybaby wah pedal. Guitarists are
pretty fussy about effects characteristics, and there's some
debate about the properties of the various inductors in Crybaby
models through the years

Once I get the sound right, I want to add a PIC (for auto-wah,
running wah, swell, etc) controlling two wahs. There are some
interesting ideas out there for inter-wiring and voltage control

for example

But I digress......
