It matters as to how it will fit in the cavity
I wired up a super switch once
and when I went to put it in it would only go in one way
backwards
had to turn it round
swap all the wires on it
so yes
the answer is yes it does
take your time
look it over
think about what you are doing
measure twice.....
you know be careful
don't cuss out loud if you hork it up

Hi Ed. The wire that I have highlighted if you can see it. Is it necessary to go between both common points on the switch or not?View attachment 65035
only if your using both sides of the switch.. i visualize the switch as 2 independent switches..

... to carry audio signals.

On, for example, a HSH Superstrat with MV and MT controls, the second pole might be used to automate coil splitting. In this case, you certainly would not want to interconnect the Common terminals of the two poles.
Ok. Im at a loss of why this guitar has the feedback it does now....My humbuckers are mounted on an aluminum pickgaurd but i had single coils mounted on it before. There is feedback on all positions of the switch even when the tone is rolled completely off there is still a hum. Everything is grounded to the volume pot and also a ground going to the tremolo plate from the volume pot. Stereo jack was installed, just with nothing hooked to the hot side of the stereo jack if that helps.
are you sure the pickups are not at fault.. ?
we might have to see a pic of your wiring adventure as well..no offense but it very well could be your wiring job if you are inexperienced in wiring guitars...is possible that something might be in error with your wiring .. hey ,it happens to people with experience from time to time too.. when i do electronics work, I always use 2.5x reading glasses and a bright lamp, so i can clearly see all the wiring connections.. you would be surprised at what you catch with a magnified inspection
possibly could of smoked a component in the process of wiring.. meh.. it happens
lastly.. small chance the stereo jack might be at fault..
troubleshooting time..a process of elimination ,of possible causes
When I get around to the time again, i can take the pickguard off and take a couple pics of the wiring and post them...Could it be that the .47 capacitor i put on got to hot and is causing this issue?
