    In the 50s wiring you ground the pots together. What do you use and where can I get it? I can't find it on stew mac.

    in all wiring you ground the pots together.

    any wire will do, it doesn't matter electronically.

    22g stranded is the normal guitar hookup wire, just because it's thick enough to be sturdy but thin enough to work with in tight spaces.

    It's called bus wire. 18awg, solid, unshielded.

    I'm sure there are some that will say there is, but....

    It's what Gibson has always used and I find it easier to work with than hookup wire for this purpose.

    i lifted this page from the terry mcinturff book;

    i now use big-ass solid core bus bar copper (like home depot house wiring copper) to ground pots together, just because it makes the pots mechanically rigid; if a pot gets loose, it still won't spin around and break off the wires.

    terry refers to tricks like this as making the guitar "tour-worthy".

    the problem with copper piping like that is that it is hollow.

    When current flows through a solid wire it creates a cylindrical EM field.
    When if flows through a tubular wire it creates a inverted-toroidal EM field.

    The more fragile harmonics created by a guitar pickup can survive in a cylindrical magnetic field. They seem to be eliminated or squashed in an inverted-toroidal field. It really comes down to that...

    So the real question is "how many smiley faces do I have to put in to this post so people know I am joking :) :) :) "

    It is a great idea but I wouldnt try it at home. Would be overkill for me.

    It's actually solid copper, not tubes, and the answer is "more smiley faces than that" ;)

    It's not that hard to use; just be sure to scrape the ends with sandpaper or steel wool to get the varnish off, so that the solder takes easily.

    You forgot to mention the Flux Capacitance that is formed between the copper ground wire and the braided shielding - that can cause very nasty disturbances in The Force. :aok
    :D

    PS I think it's a great idea. I especially like the fact that if the pot comes loose, it's held in place by the copper ground wire. I think that's brilliant.
