Takes a lot of measurements!
Are there any other simpler methods that are as accurate?
i think it's about time i learned this stuff! thanks for the explanation.

I'm going to start writing up various little easy tutorials on things like Jfets, mosfets, bjt, opamps and rc filters. I've learn't this stuff very very slowly, with a lot of help from various guys around here. It would be nice to give summit back
i think we would have to immortalize you into stompbox sainthood if you did all that!
i've seen what looks like some really good stuff along those lines on some japanese sites. too bad all i can understand are the diagrams! i found them by going to fffworks and following some links around.
maybe it could give you some ideas? some simple explanations putting these things to practical use always helps as well.

I would do it to be the basic of basic, like learning guitar to write songs - you don't need scales, just the chords. Give people the tools they need to design and make their own stuff. It would be awesome if we could get some of that japanese site translated, it looks like a great resource!
The fetzer valve article on runoffgroove is one of my favourite reads - I'm forever back and forth to that for ideas. I'll get some stuff worked out and see if I can squeeze some quick and easy guides out. First up - basic RC filters and the equation to work out corner frequencies!
