  1. Thanks for the lengthy reply. I have read through most of the forum, I would suggest that if there is a way to get the most current specs of how to build this thing tacked onto the end of the forum it would help. I had read in the forum that others had used the .25 wire, although now that I have used it I realize that I don't remember anyone saying it had actually worked out. I had gone to radio shack to get the wire, that's all they had and I didn't want to put in an order at mouser just yet, I'll have to now. The F/R circuit is built with the 100uf output, and the 10uf between pins 1 and 8, I omitted the 100k pots figuring that it would be running full up to get the strongest effect. I had run out of parts so I didn't add the 10k .1uf to ground part yet as I had thought it might not work right the first time and I needed other parts anyways. So, I did find out that the optimum/maximum effect was attained with the guitar volume at about 1/3 and the tone close to all the way off, this is a tele fyi, so I guess if I add the 100k pots and 10k .1uf to ground it would get the same result as the guitar pots. Also, this DID work with the metal cap on the pickup driver, although it was just a bit more subtle with it than without. Additionally I used an Elmer's wood glue, and as far as measuring impedance, I am confused still, wouldn't there be some impedance from the spool of still connected wire? And when measuring, I should touch the first end and then should I touch the actual wound coil, or the single strand end still running to the attached end? Thanks for the help, you have certainly done a lot of work on this.
  2. Can someone help me figure out how to measure the impedance of the driver? I have an analog multimeter, which setting would I use and where would the test leads go? I am assuming on either of the two ends of the wire wrapped around the driver, but no setting on the MM seems to show me a corresponding impedance. The F/R works great, tested on a speaker, the driver and F/R both work "properly" to drive the strings, but the effect is not as intense as I was hoping for. I made substitutions, 30 gauge or the 25 wire not 20, I used a single coil tele neck pickup. The calculator website said about 180 turns to get 8 ohms, I believe I am in the ballpark on that (lost count a bit, oops) Also, the height of the area I wrapped around the bobbin is just about 1/3 the original size of the entire pickup bobbin, not exactly the 3mm. I've built a bunch of other pedals so this isn't over my head. Thanks a bunch.
