    Gretsch style "mud switch"

    Hi,

    the set up would be:
    Filtertron (TV Jones "classic Plus" or "Power'tron")
    Volume pot.

    Ideally - I'd like for a volume push/push pot to affect the guitar's tone output: I see two options for this:

    (1)
    My understanding is that this could be done if I used a push/pull 250k/500k (dual value) pot. I'd get basically a tone bypass form a 500k pot and another tone bypass from a 250k pot - with the 250k pot providing a "warmer" or "darker" tone.

    That presents problems because the only such pot I can see is a "fender CTS pot" with a short shaft - so I wouldn't be able to use it if I put the pot in through the back of the guitar (I'd have to use a control panel).

    (2)
    I also understand that if I put a resistor across one of the positions of a dual 500k pot I could achieve the same two "tones" (but apparently this might have problems when tapering the volume - which becomes "on /off" - I assume this is when an audio pot is used - I wonder if it's a problem if a linear pot is used?) As per this Picture (although I've no idea where to position this on a dual pot):

    The alternative is to use a "mud switch" similar to this (pretending that there is only one pickup "where the selector switch is" connected to the volume pot):

    ... which I think is:
    Switch lug 2 (one of teh middle connections) connected to volume pot
    Switch Lug 1 connected to "cap 1" (which is grounded to back of volume through the "other" middle connection) and
    Switch Lug 3 connected to "cap 2" (also grounded to back of volume through the "other" middle connection)



    ........or to use a dual tone pot which I think is this here:

    So If anyone is aware of a dual value push/pull pot available in Australia that'd be great.

    If not - and someone knows how to position a resistor to emulate the above - and also knows how to mitigate the taper - that would be much appreciated.

    Otherwise could someone confirm the "mud switch" picture (pretending that it's a single pickup and that in the picture that pickup'd be where the "selector switch is)......

    Last choice is a dual tone pot - but I think that picture is clear enough even for me (I assume a ground wire also goes from the casing to the back of the volume pot?).


    please note - the above pictures represent the extreme maximum for me in this - I have absolutely no understanding of electrical diagrams using symbols -or anything complicated...
