[sdiy] filters, inductors & Q

[anthony]

I don't see inductors used much in audio filters, but I think I read 
somewhere that an inductor will have greater Q than a similar circuit 
without one. What are good reasons to not use inductors in audio filters?

I ask because I was looking at the Crybaby  wah-wah pedal schematic and it 
has a huge 660mH coil in it. (It may be uH, but I'm pretty sure it was mH.) 
I thought maybe this was just there because it was in a guitar peadl and 
needed to be there to avoid damping the strings or soemthing, but that 
really didn't complete sense to me. In a wah-wah pedal you'd want a nice 
sharp filter so that makes sense if what I remember about coils is true. But 
I don't know as much about using inductors in filters as I am with 
capacitors and resistors. Most of the stuff on coils that I've read mostly 
pertains to oscillators which could be thought of as a filter with a lot of 
Q. But I haven't seen much application info.

I have these two really cool looking filters that used to be in an old touch 
tone phone. I thought maybe I could do something with them. They have a lot 
of taps though.
