The little voices in my head keep telling me "build more guitars"
A photo (or three) of the control plate and its wiring may help. Make sure we can see all the joins. It's a pretty basic circuit, so there's not normally too much that can go wrong.
Are you reliant on the control plate providing the ground connection between the pots? I always wire the backs of the pots up regardless.
Simon,
Been busy finishing other builds. ...... and I was worried I would throw this one across the room.
I rewired it completely to the piccy from McCreed on his response to this thread.....I actually printed the piccy out and soldered up that rig.

I have taken an oak Grigsby 3 way switch out of the harness and put the flat plastic kit one back in place and got the same story. I changed the volume pot.....and the capacitor.
The only things I have not changed are the jack socket, tone pot and the connections to the pickups......maybe take it all out and rewire the lot from scratch.

And the guitar lead is OK with another guitar?
Again, it's worth taking and posting a photo of the control plate wiring, just in case there's something glaringly obvious.
Otherwise you could temporarily disconnect the volume to tone pot connection, which would take the tone pot and capacitor out of the equation.
Pics of the actual build are always good. If it's wired as in the pics you referenced it should work and make some sound.
Since you haven't checked the jack, you might check to see if you got the connections reversed. I'd try that before anything else.
Next I'd disconnect the tone pot. That's probably not it, but I'd do it anyway.
Next jumper the hot lug to the center lug on your volume pot. That should take everything but the switch and the pickups out of the circuit.
You could try checking the pups with a multimeter, as has been suggested. It may be unlikely that both would be dead, but it's not impossible. A broken winding will result in a "1" on an Ohms meter.

Wow, and wow again.
I have replaced everything on this build.....and then put the wires from each cavity to an earth point back in.....same result...no or low sound.
The answer and reason.....bloody shielding....shape of jack socket holes...recessed jack socket...switchcraft jacks...and some bloke who looks like me who shielded everything.
Remove jack from body...plug in lead and really great sound.
Resolder the wires and re-shield the bits I had scraped away in the cavities. Turn the jack socket 1/4 turn...and re-insert into the body.
With everything shielded, these huge P90's have zero buzz/humm...dead quiet. I dont know if the Tonerider Rebel 90's are shielded or have mystic properties, but they are dead quiet and have some serious single coil bark....and twang. Wow.
This build is now complete with the import three way switch in position and the Oak Grigsby kept for another build. Pics of the finish to come once a setup is done.....the Bigsby style trem works well, but is hard to string up.
