I've had an idea for a swithcing arrangement but I'm not sure how to wire it up.
My idea is to wire a switch so that you can turn a pickup off in one position, in another positon have it as a single coil, and in another position have it as a humbucker. There could be one of these for each pickup, as required. I would imagine that I'd have to split purchased humbuckers for this.
I don't know if such an arrangement is possible, as I'm not really versed in electronics, though I think I can follow wiring diagrams I've found online.
I hope someone can tell me if this is possible, and how I might go about doing it?
The type of switch you will need is a Double Pole Double Throw (DPDT) Center On type. To see how this switch works go to my website page: www.1728.com/guitar.htm scroll down to DPDT Switch and look at Diagram C. This is a relatively easy to find switch but is usually NOT the kind sold at online guitar switch sites. If you want a diagram for the type 'D' switch, let me know.
AM - thats a very useful page! I will add that to my collection
Wolf - for some reason I cant see your new drawing. A shame to miss it since your stuff is always worth a look.
Freddie - your idea could make a nice simple design, with two on-off-on minitoggles. It would work well with a master volume and tone control between output and ground, which would help to ground any noise picked up by the disconnected all-off position. If you wanted to extend the idea, another standard DPDT mini toggle could provide a phase switch, and also select between single coils in the bridge position. If you are intersted Ill post a circuit
The phase switch turns the bridge pickup, 'upside -down' in the circuit, which reverses its phase, and causes the other coil to be bypassed in single coil mode, giving a slightly different SC sound.
With this, apart from the humbucker in and out of phase combos, there are in phase and out of phase single coil combinations, both hum cancelling. I think it adds up to 9 different sounds in all, from funky out-of phase single coils, to mellow humbuckers in combination.
It's very important to get the phasing of the coils right, to optimise hum cancelling. On the diagram, red indicates reverse wound reverse polarity, and the '+' indicates coil finish, relating to the phase of the sound.
The phase switch is a standards DPDT, and they can all be mini-toggles, which look the same and mount in 1/4" holes.
John H My diagram was uploaded to photobucket and it sure seemed to take a L--O--N--G time. If you still can't see the diagram (or anyone else for that matter) I'll start uploading images to websites instead. Too bad, because RandomHero thought photobucket was a great site. (It seemed that way to me too).
