blower Switch for S-500

[ocharlad]

Hello, I'm a -french- owner and lover of a beautifull S-500, wich is a fantastic guitar, I'm very happy with it. But on stage, I need to have my volume pot on a partial value (exemple, at 6) and I must put this value to 10 when I take a lead... (I hope, my english is not to bad and you can understand my problem !). And after I must take the rythm part and return to 6... It's often hard to do that, and I would put on the wiring a switch to bypass the volume pot and have easyly the total sound, and return easyly to the partial sound, a little like that :

But only for the volume pot. I can find some wiring diagram for some strat, but the S500 wiring is special, and Im not sure that it's the same way to proceed with it. Is there anybody here who can help me ?
Thank you !!!

If it is simply the volume setting that you wish to bypass (and go instead to maximum) then this is simple.

You need only a single-pole double-throw (SPDT) switch for this. Toggle switches for this are readily available, and can be small and discrete.
This switch will have three connectors, all in a row.

Disconnect the wire from the middle connection on the volume pot (and if there is a capacitor also connected there, disconnect this end of the capacitor also).
Now connect this wire (and capacitor connection if there is one) to the middle connector of your new switch (the "common" connection). You may need to use some sleeving to cover the join if you have a capacitor connection to make as well as the wire, but this is not a problem. Just be careful if you choose heat-shrink sleeving, to avoid overheating any of the lacquer or pickguard etc.

With a new piece of wire, connect one of the new switch's other connections to the middle connection of the volume pot (the place from which you just disconnected that first wire / capacitor).

With another new wire, connect the new switch's remaining connector to the volume pot's "hot" track end. This can be identified as having connections to the 5-way switch and / or the tone controls. (The other end of the volume pot's track is connected to earth, usually in an obvious fashion such as soldering to the body of the pot. You don't want to connect to this end).

You can now switch between a preset volume control setting, and maximum output. The 5-way setting and tone control settings will remain unchanged. Fit the new switch whichever way up suits you best! One position is "normal", the other "full volume".

I hope this is what you were looking for, and is some help.
If I have simplified the description extremely, please forgive me! I am aware that we have some degree of language difference, and I only mean to be clear in order to help.

If this is not quite what you meant, do let me know and I will try to be some help.
