spin-a-parallel/series

[larry_emder]

I've seen a washburn guitar that employs this wiring - anyone got a diagram for it? And can you use a normal 500k potentiometer for it???

Thanks

The only way I can see to do this would be using a dual-ganged pot. I'd probably use a dual 1meg, but a dual-500k might work. Both pot wipers move left or right together. Wires go, (top to bottom), black, white, red, green.



Edit: FTP software fixed.

This guy posted this on another forum but I can not remember which one as I just stole the link to the diagram. He claims this is the way the Washburn VCC control is wired with the regular dual pot. And another option is to use a blend pan pot and get a rotary series ,split coil, parallel blender control. I have not tried this but do not see why it would not work.

Now THAT is a fascinating idea...

[larry_emder]

well can you be our donkey to test it zhang?? i got too many guitars to wire up as it is!!!

Would be a good idea for a really high output humbucker i think......would give it lots of versatility

Maybe -- I've got a pot I'm not using on my LP at the moment. It would give a lot of versatility to the tone of a metalhead pu...

Is this the pot i require?

This also?

Couldnt find any 1 meg ones.

[larry_emder]

on that note....would my TBX control work?? Even though its got the centre detent.....or is it wired up wrong?

The 1 meg recommendation was a guess. Since LJ found the proper diagram, I'd go with the 500k.

I believe a TBX control is one 250k and one 500k. Probably wouldn't work well.

That first auction item 7410436502 is the pan pot blender style and would give you the split coil in the center detent. The TBX pot is this same pan pot blender style but it has 1 meg for one section and 250K for the other. it would "work" but it might not be as smooth as you might want.

The second auction would be the dual pot style you would want for a smooth series to parallel blending. Those pots are meant for PCB mounting and it might be tough soldering wires to the lugs. This link shows the pot style I would use instead of the PCB mounting ones.

Ah . . . thanks for that clarification.

[larry_emder]

hmmm, might give the ol' tbx a go and see what happens first.

[larry_emder]

Gave it a go with the tbx and its pretty useless....

on 10, standard humbucker sound...
BIG vol dropoff immediately after 10 .....

Then in the centre detent the vol goes back up a bit as it is in single coil mode.

Then immediately after that it goes back to the quiet parallel, and stays pretty much the same volume on its way down to zero.

only lasted 5 minutes in the axe....but what the heck, was worth a shot.

Think i'll just stick to spin a split...

I suspected that this is what you'ld find. However, I think if you went with the type and value of pot that LJ refered to, you'ld have better results. The TBX is just "wrong" for this app.

[larry_emder]

Well i just wired it all up using these pots http://cgi.ebay.com/500-ohm-Linear-P...QQcmdZViewItem

Was wondering why i wasnt getting a reading from the multimeter......so i checked the pots......only to realise they were 500 ohms instead of 500K ohms

DOH

Will get around to it one day!

So what am i gunna do with these 500 ohm dual ganged pots???

Put them in a guitar with pickups that are active buffered in some way(stock or modded, chap buffers ar out there[guitarfetish]) and then wire them up blended.
