Good catch. Here it is corrected if Duncan & Co. would just like to replace it with this one.
Is there a problem with this diagram?

While not a mistake per se, it would be nice if they brought back the old tone chart, in PDF format, with all the newer pups on it. It was a great quick reference that you could view offline.
Also, many of the pups on the website are missing their model number. Makes it difficult sometimes, when you're checking on a pup in a drawer.

Hi!
Been rewiring another guitar today and found missing wire here:

The tone pot should be connected to central tip of a switch (attached pic) - tone adjust doesnt work without it

The Blackouts Modular Preamp has the tone cap shown connected wrong. The lower lead of the cap should move one lug to the right.

I recently wired this up in my PR/LP hybrid that I built and found two errors:
One - Missing jumper from Pin3 to GND on the bridge voume
Two - Wire from middle toggle switch pole goes to the wrong lug on tone, making the knob work backwards. Lol
Ok, so now to my question. The coil split and phase push/pull switches work exactly as intended, but the series/parallel push pull on the neck volume make the bridge pickup drop out almost entirely. Is this just a limitation of the wiring/switching? If you put the toggle to the middle position, both the bridge and neck volume will still work.
Any insight would be appreciated. Thanks you.

I haven't wired this but I was reviewing it because weekendwarrior was looking to modify it in another thread. I'm not sure if its an error or just mis-labeled.
It says:
"Position 4: Bridge Humbucker plus Neck Split"
Tracing the signal path, P4 will be both humbuckers split - Neck Slug coil and Bridge Screw coil.
The Bridge Black wire is not connected in Pos 4 so it can't be full bridge output. Looks like everything else would work but the wording is confusing.
2H_5WSPL_1V_1T.pd
2 HUMBUCKER | 1 VOLUME
1 TONE | 5 WAY BLADE (with coil split)

As supporting evidence I submit the many threads here where people connect Blackouts to an EMG harness, and EMG has never used the string ground. I found this one (and only one) Blackouts diagram BO_3G_2V_2T.pdf the LP style setup does omit the string ground.
EDIT - no sorry I read that diagram wrong it has string ground to pointing towards the battery...

Where did you find that? I can find 2BO_3G_2V_2T.pdf, but it still has the bridge ground.

Edit; Just checked. My Schecter C-1 Platinum, that came with the EMG 81/85 set, has a string ground. I've installed my Dave Mustaines, but haven't soldered it all up yet.

aargh...I looked at that diagram 10 times and missed the string ground going towards the battery :sad: On the others its going to the right side...
EMG manuals have always said to remove the string ground, but I've never heard their technical explanation why. There's plenty of examples to the contrary like your guitar. I actually remember one of my coworkers some time ago arguing with their support about this in the course of trouble shooting an 81/85 pair a customer thought was defective.

Yeah . . . I've spent over half a century in electronics, and I don't understand why, or why not, either. I can't see where it would make a difference.

I just dont see how that makes any difference
Reducing the resistance to cap and ground in the same direction
Would you please offer a bit of context, please
The tone worked in reverse. And the tone taper didn't seem to be working correctly. You may not be able to see it but you can sure hear it! lol

In the diagram referenced above for a standard (Les Paul type) dual PAF humbucking guitar with a 3-way toggle, the capacitors are .047 µF, whereas I have always used .022, which is the norm, I believe. However, the .047 could be a throwback to vintage wiring - - I don't know. Just thought I'd put it out there. A lot of folks find the .047 produces muddiness, especially in the neck pickup.
