Mix Ratio With 2 Humbuckers and a 5-Way Switch

I wondered if it is possible to have mix ratios with 2 humbuckers and a 5-way switch. Something like
Position 1: 100% bridge pickup
Position 2: 75% bridge pickup, 25% neck pickup
Position 3: 50% bridge pickup, 50% neck pickup
and so on...

Sure, if you use fixed resistors and a true 5 position switch.

You will find however that the two pickups interact. The lower resistance pickup loads down the higher resistance pickup. So at some point you will reach a threshold where you only hear one pickup.

You can experience this on a bass with a pickup blend control. There’s a small useful range before you solo one pickup.

Two ways I can see this happening

1) - with a super 5 way switch and using lots of resistors for custom sounds, you'd have the most control. I'm not big on the idea. I mean you might as well just use the volume pot as it's like putting a basic varitone without the inductor from 0.01uf to 0.047uf , i can get close to those with a linear pot by just looking at the numbers on the side of a pot if it's a dual humbucker guitar.

2) - The other way is any 4 wire pickup has plenty of wiring mods and coilsplits as well as parallel drop the volume of the pickup. Coilsplits provide approximately 50% of a pickups output, parallel depending on the two coils 25-30%, however parallel is hum cancelling. Seymour Duncan triple shot mounting rings make this an easy job. Or a lot of push pull pots. Again I'd lean towards the super 5 way if you're comfortable with a soldering iron. I didn't have the best of luck with guitarelectronics.com wiring diagrams the one with parallel in the positions 2 and 4 I attempted twice and both times I got coilsplits not parallel. I knew everything about the pickups. Hopefully the administrator fixes that diagram. This is september of 2019 I tried these and have wired 100s of guitars.

I remember 5 years ago I drew out a diagram for a guy and I guess the easiest way to describe it is on a les paul each coil had two volumes. No tone controls. Just a bridge north coil , bridge south coil , then a neck north coil , neck south coil. Say you had a zebra pickup set you had control over each color of the coil if that makes any sense. I thought it was a bad idea but whoever posts on a good day I'll usually take it as a challenge and draw out something. I deleted the diagram but it was pretty much 4 "spin a split" modded pots. It seemed impractical as it became very difficult to turn the volume down.

I played a BC Rich with this one time. No idea how they did it.
