Hi wiring Gurus
Firstly my usual apology for my inability to produce neat diagrams.. These are of course only extracts simplified to basics.
Over the past 7 years or so I must have used my schematic for series to parallel plus col cut using 2 push pulls (see Fig 1) around 8 or 9 times without any issues or problems.
I and several others prefer this wiring to the usual more straightforward option of coil cutting when the bridge pup is in series mode as we consider it gives better options. The option of having parallel wiring for the bridge is beneficial if it is over wound like a JB for clean playing.
Sadly on my most recent project using this wiring I seem to be getting hum when the bridge pup is cut to the slug coil.I suspect this may be due to some kind of antenna effect as in the diagram the coil cut leaves the bridge screw coil hanging while still connected to the hot.
This issue will hopefully be removed by adding a jumper wire (see Fig 2) which will connect the hanging wire to the hot side when coil cut is engaged.But I have not yet rewired as I am still kinda thinking things thru.
What puzzles me is why I not experienced this issue before? Did I just get lucky all those times?
