Oh, wait, thats the audio signal isn't it. :) But, simple electronics math for l-c circuits can very accurately predict exactly where in the spectrum, possible even sub-ultrasonic and therefore hearable by good, or not so good, ears. The L in the formula is of course the inductance of the pickup coil driving the cable. The C is the cables rated capacitance per foot times feet of cable, or its actual measured value. It forms a resonant circuit thats pretty easy to either predict or measure. Its frequency is where the impedance of the L=impedance of the C. However, depending on the pickup coils inductance, I'd hazard a guess that it would take more cable (lengthwise) to get to where that condition would have an effect on the sound than is generally used. Most of you will stay within the 25 foot length of your best cable. For those that need more these days, as in complete stage freedom, there is always the little black box transmitter and receiver combo's to put to use. A friend of mine who plays a pretty mean electric bass has been using one of those during practice sessions for a couple of years now since thats one less cable to stumble over when the session gets late. It works from anyplace in the building, the building is an old steel building, one end of which has a 100kw tv transmitter thats also running. It hasn't bothered his 'cable stretcher' a bit that I've ever heard. -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules.
