Put a switch there anyways hooked up to nothing as a "Producer Switch" :D

Thanks for the replies and ideas.
I still haven't been able to locate a switch.
But, as I don't really need an on/off switch on a guitar, it's no big hassle.

The other 2 toggle switches I always assumed were tone changers.
Someone has been inside this guitar before with a soldering iron, so I can't be certain to the originality of the wiring.
I've been trying to figure out how they could have been wired. In the central position, the (only) two terminals are connected, in the only other position (down) the two terminals are not connected.
My electronics knowledge is not strong, but for a tone control in a guitar, I'm pretty sure it's a capacitor connected between the live signal and earth.
I can't figure how to do this, with the central position being "no tone change", and the "Down" position being tone changed.

But, again, I'm beginning to care less! This Vox is supposed to be a copy of a Gretsch 6122. I've had a look, and the controls are different!
The 2 pots on a Gretsch are individual volume controls for each pick-up (one volume and one tone on the Vox), but those switches ARE tone switches. I cannot find out for sure if the old ones were simple on/off switches or, like some modern Gretsch guitars, actually 3 way tone switches, where centre position is direct, and down is one kind of tone change, and up is a different kind of tone change, using 2 capacitors with different values.
However, in looking into this, there are many queries as to the usefulness of these switches, and they seem to have been given the nickname of "mud" switches!

SO- Decision time. I'm going to forget about using all 3 switches (they'll be in situ, but wired similar to Sam's DFA switches ;) ) and wire the guitar more or less like a tele.
The Vox isn't in pristine original condition and worth a fortune, so no anoraks will be offended!

Guitar is back together, with 3 DFA switches.
I now have DEEP respect for those who work on semi-acoustic (335 style) guitars.
Re-assembly with wires getting tangled up, the bits of string coming of the end of the pots just as it pops up out of the body, dropping a pot back in the body before getting the nut on...
If I had a swear box I could pay off a considerable percentage of the national debt!

That's why they are called F-holes.

For long runs inside a guitar like that, surgical latex tubing is often better than string. Get the right size for a pot shaft and you can stretch it over the shaft and it will cling nicely, despite being pulled/stretched.

It comes in a few different internal diameters. You can also use it for springs on Strat and Tele pickups.

On this particular guitar they aren't real F holes, they are painted on!

Wonks, your timing sucks! :D
I would say, I'll use that next time, but there won't be a next time.
(I'll save that link though.....)
Thanks.

I did finally find some switches that looked reasonably suitable. But I won't mention that. :shh:

Swear box got a bit fuller!
Thanks Wonks, but I don't ever want to see inside that guitar again!

I admire your new-found confidence, but I think trying to do this with your eyes closed is probably not a good idea. ;)

Can I take a mo to applaud not just Wonks encyclopaedic guitar esoterica but also he just keeps adding to it. Knowing where to get those switches will come in handy one day!

That's a very good point Adrian.
Thanks to Wonks for tracking down that switch, I thought I'd searched everywhere but you obviously know all the best places to look!
