Jazz custom wiring diagram

[brickers]

I can't sleep so I've been drawing wiring diagrams. I wonder if anyone is able to validate what I've drawn please? It's my first time working with these things, and the documentation from the pickup manufacturer doesn't seem to quite include everything you'd need to know.

 

My aim is this:

• A jazz neck pickup paired with a MM bridge pickup
• Vol/blend/tone
• But before the blend, the MM pickup has a four-way switch to choose either single coil or series/parallel

 

Pickups are Delano JMVC FE/M2 (neck) and Delano MC 4 FE/M2 (bridge). Documentation for that is here: https://www.delano.de/downloads/installation guide_2018_1.pdf. The J is a 'shielded 2-conductor' and the MM 'shielded 4-conductor'. I've omitted shielding wires from the diagram as I understand they just go to ground.

 

Thanks in advance!

That looks about right, and the pots are in right order: blend, vol, tone, out. 

 

As you use three pots in parallel, consider, what's the right impedance to the system: 

1) 250 k pots give an overall Z around 250 k / 3 = +80 k 

2) 500 k gives approx 170 k 

3) 1 M -> 330 k 

 

Bigger Z gives a slightly brighter sound. 

 

If you want some extra, consider Noll Mixpot. It does not load pickups, but requires a 9 V battery. Klaus Noll made me a system consisting of a Mixpot, and a tilt eq with a switch: turning eq clockwise increases B and lessens T. Pulling the pot and turning the pot clockwise increases both B and T. Surprisingly practical, single pot.

Thanks @itu

this is intended to be a bright build and I was thinking of using 500k pots, though I didn’t realise that’s how they stack. The mix pot looks cool, though I was intending for now to keep this passive, learn some soldering skills, find a focussed setup that works for me and consider active electronics later. Good to keep in mind though.
 

your tilt/smile eq is very cool - doesn’t John east do something similar in a precision preamp to save space? Do you find that it’s intuitive to use?

Tilt comes from a Steinberger trial long ago. I liked the idea, and Klaus made a functional solution. I didn't have time to make my own design. And Klaus could use a switch pot to include another - smile eq - option. Mixpot was already a must, not an option. 

 

Tilt is very easy to use. If I need more bass, it happens while treble lessens. You know: eq could be used as a volume, but it shouldn't (smiley could be done by cutting mids...). 

 

I haven't have the chance to meet John East personally (my bad), and I don't know all of his creations, but his attitude and workmanship are world class. His mixer based thinking is very interesting and one day when my account says yes, a preamp is in order.

Hope this still works.
