Working New Build - Does my diagram look accurate/complete?

[TheIronMustache]

So this is the most complicated diagram I have made to date and I am running short on time for trial and error. Hoping to save myself a little headache and get some feedback in case I got some FUBAR lingering here.

What I am working with:

• Charvel ProMod Sand Dimas PJ (stock electronics ripped out cause yeah, no bueno)
• Aguilar DCB PJs
• Darkglass Tone Capsule

The short version of what I am after is to have your full traditional active/passive circuit with the addition of a passive tone control and a split coil direct output option. My main concern among others would be how splitting the output of the P pickup could/would affect voltage in this scenario.

The configurations would be:

• Volume and Tone Switches DOWN: P/J Pickups>Blend>Volume>Preamp>Output
  Preamp active and Volume/Blend functioning normally.
• Volume Switch DOWN/Tone Switch UP: P/J Pickups>Blend>Volume>Tone>Output
  Preamp bypassed for tone pot utilization. Volume/Blend functioning normally.
• Volume Switch UP/Tone Switch DOWN: P Pickup>Output
  Isolated Split Coil direct to output. No working control here. Hot precision single coil juice directly injected into my blood stream.

If I am on the right track here I am thinking about inserting a third push/pull on the bass pot to add the option of including the tone control with the active portion of the circuit just before going into the PCB.

Very much open to any suggestions or ideas on anything that is unnecessary or could be added.

You need to tie the middle two legs of the switch on the volume pot together or else it won't do anything and you'll get no signal.

Otherwise this looks good.

Personally I would wire it such that the passive tone is in the circuit even when the eq is in the circuit. If you want it "out" of the circuit you can just turn it all the way up. I like having a true passive tone pot prior to an active eq since it gives extra flexibility where I feel it's most needed.

That makes sense. In that case I could eliminate one of the switches and and have it just be the option of all in circuit or split single strait out. I guess I could always repurpose the obsolescent switch to be series/parallel I suppose.

My electronics knowledge is negligible at best being just some light reading online but I feel like splitting the pickup output should be OK. My only concern would be that it makes sense to me that with the line going to the blend pot not being cut off it could still bleed to ground. Am I thinking about that correctly or would it not be an issue if the direct out circuit is on creating that path? In this case I could probably just throw it together and see what happens as a worst case scenario.

The blend pot will essentially be putting resistance in parallel with the pickup in your "direct to the jack" mode. If you want to avoid that, you could rework that switch to cut the bridge pickup in and out on one set of poles, and to switch the neck pickup between direct to jack and the normal circuit. I'd draw it for you now but I'm on my phone and that would be a challenge.

I really appreciate it but I think with what you gave me here I can rework the diagram and post it back up here. I like that idea way better to be honest.

Also, after some more digging it would certainly seem that not grounding the blend is going to be the way to go for my application so I will change that unless there is a reason to leave it grounded at this point.
