Hi guys,

I have a bunch of jobs on the go and not a lot of time so was wondering if anyone could help with this please?

Firstly, is it actually possible to have a schematic with no pots? Can a guitar produce sound with just pickup to jack..?

In theory (if you can have a schem without pots) I imagine it's pretty straight forward and I will try pen it out soon if no one has it handy.

The fellow has a guitar with one P-90 and one volume pot.
He wants a switch put in that switches between:
Volume pot in the circuit
Bypass volume pot and go direct/full signal.

I have a two way switch with three pins on the bottom; On/Earth/On (least I'm guessing that's the case).
It's a kill switch out of a Les Paul BFG.

So I need to incorporate a P-90, a volume pot, the On/On switch to the output jack..

That make sense?

Cheers all. Thanks for any help!

Ok, now that I'm back at work I've had time to draw up a sketch..
I used my tablet, so it's pretty bad... Hopefully it makes sense?

So, anyone who is electrics-minded, would you mind looking at this to see if it makes schematical sense, please?

Hey, I did say it was terrible...

So hot from pickup, split in two to the two outside lugs of the switch.
One out to the pot hot, then from the pot middle to the input jack hot.
Second hot out from switch direct to the input jack hot.

Ground of pickup to middle lug on switch, then out to all ground points from here? To pot, to input jack ground.
Do I also need to run from input jack ground to the back of the pot?


Any help would be really appreciated please guys.
This is a unique guitar where I have to pull it all to bits to wire it up, so I effectively have to rebuild the entire thing and string it up just to test if this will sound out properly.

So it'd be good to get it right the first time :).

Thanks all.
