How to wire up Silhouette Special without the Silent Circuit ?

[jamminjim]

Could use a little help. I'd like to wire up my Silo Special without a Silent Circuit (SC) using an Oak Grigsby Super switch. I found this diagram at Guitar Electronics dot com but this one is different concerning the 2nd position. EBMM uses the south coil in parallel with the middle pickup and this GE diagram uses the north coil and middle pickup. You might say it is very similar but I would like the circuit position 2 to be exactly like the EBMM wiring, with the south hum coil and middle single, the physical distance apart is different.
So, what do you do to eliminate the SC from the equation the way EBMM has the circuit wired.
Or could I just flip the red and green wires on the DiMarzio hummer? Wouldn't this be out of phase though?



I can send the EBMM SS HSS wiring diagram if you would like to have it to evaluate, don't want to post it as I don't know if that is approved of here, send me a PM for it.

And lastly, thank you in advance for your help.

respectfully, ~Jim

No, this is wired a little more differently than simply swapping wires will allow. (Compare how the north start wires are connected between the two diagrams). You want to keep the stock coil combinations to keep hum cancelling.

Start with the EBMM diagram. Any wire from the silent circuit is simply disconnected. The black wire from ground to the common terminal of the pole connecting the yellow SS wire is redundant and can be removed also. The black wires from the two single coils go straight to ground.

Unless the baby-induced lack of sleep has me confused, that's all you need to do.

(Edit: Got it wrong, see my next post below).

Ah so - yes - the Humbucker stays wired as is in the EBMM diagram. Take the single coil grounds to the back of the volume pot like any Strat.. Reds stay wired as shown. So then it looks like half of the Super Switch isn't even used.

Sorry, I guess the fatigue is getting to me!

We need three poles of the four poles to allow splitting the humbucker.

Pole 1 is where red/black/white humbucker and neck single red are connected.
Pole 2 gets middle single red.

Pole 3 is where humbucker green and neck single black are connected at terminal 3, with another green wire to pole 1 terminal 2. What was the blue wire from that terminal to the silent circuit is now to be replaced with a new wire to ground. What this pole does is provide a permanent path to ground for neck single coil (black) and humbucker green, and in position 3 provides the path to ground for humbucker black while connecting humbucker green and white, short circuiting that coil.


So...

Start with the EBMM diagram.
All wires from the silent circuit are simply disconnected.
All wires to pole 4 (SS yellow connected) can be removed.
The blue wire from SS to pole 3 terminal 3 is replaced with a new wire to ground, leaving all other connections to pole 3 intact.
Middle single ground (black) can be connected to ground anywhere.

So 1/4 of the switch or one pole isn't used. Thanks Dr. Kev. I can run a jumper from the pole 4 side black gnd wire over to where the blue wire from the SC was connected. Nice.

I'm making a new Silo Spec guard using two BSC singles and a DiMarzio humbucker ( I don't know what it is, it came to me on my blue Silo as a replacement, all it says on it is F for F-spaced and C 3 whatever that means) No DP label.
