Sidewinders, Multi-coils and other hard to find pickups

I've always been intrigued by this neck pickup.I'd like to see something like this under a EMG35 shaped cover

The Multi-Coils is going to keep me busy for a while, figuring out how I want to build those.
That will be enough project for now, along with the other pickups I make.
If I take on another project, it will be putting one of my Sidewinders in the shallow chrome T-bird cover.
I think I know how to do that now?

There are 3 ways to wire the 8 bobbin multi-coil wal style pickup.
All 8 in series (8x2.5=20K).
One row each in series, tie the two rows together in parallel (4x2.5=10/2=5K).
2 coils in series for each string, then tie the 4 pairs in parallel(2x2.5=5/8=.625k)
I wonder how each wiring scheme will sound?

I guess rotary switching would be a hard thing to pull off?

I don't do this stuff so I'm really not sure if/how it would work or not.
 
Yes, there is that 4th way! :<)
Those values are for 42AWG, and I will probably use 43.
So my readings will be higher.
I was just wondering what the difference in sound, with the difference in wiring will sound like?
The way they get wired will probably depend on whether using a built in preamp or not?
Hopefully this thread will document some of these Q&A for future references in Multi-Coil pickups.
Also maybe we can get some comparisons between different types of pickups.
Like what a Sidewinder sounds like compared to a Multi-Coil.

I got the magnets today for the MC's.
I built 8 bobbins and wound one.
Hopefully I posted 3 pics to get an idea what they will look like?
I will make the bottom bobbin plate tomorrow, and wind some more bobbins.
One bobbin measures 2.5k ohms DCR on the nose.

Sub'd. Ive been winding pickups recently and have been wanting to try sidewinders and multicoils next. I'd love to start a project and contribute to this thread. Great info here. Both those multi coils look good, I'd be interesting in a sound clip of the finished product, if that's possible. Did you guys (Big T and Iweildthespade) both wind to 10,000 winds?

Mine are wound to 10,000 turns per coil.
I'm still in progress on the first pickup.
I'm thinking about 15% reduction in turns for the Neck pickup.
Still looking for a LH bass for testing to take my New Router to.
Thought I found another Ibanez SR300L, but couldn't deal with the GC in NJ.
My first set will probably go to Ritch in Mich. Maybe he can give us a test clip!
