Heres a question I have been pondering, in my search for the ultimate guitar switching:
When switches are used to connect, disconnect or bypass pickup coils, in an arangement involving say. coil cut and phase change etc, sometimes the coils which become inactive are still connected at one end to the circuit, or maybe both ends are connected to the output, having been bypassed by a switch.
Having such partly connected branches is ok if they are only connected to ground, but what if they are on the output side of the circuit? Does this act as an 'antenna' to pick up noise (even if they are not adding to the sound)?
The sort of effect Im talking about is like if you attach a bare wire to the tip of a guitar lead and plug it in on high volume.
Im asking because I have a nice circuit that Im working on that would work great unless this is a problem. Short of fully building it, I cant test it easiliy because any temporary arrangement with clip-wires etc would pick up even more noise.
