I am working on the prototype coil as we speak. To make sure everyone has a baseline for what it looks like to wind a P-90 coil and build a pickup, I recommend you check out this short little tutorial from Stew Mac: www.stewmac.com/tsarchive/ts0175.htmlI am going to use four-conductor wiring, not the braided lead seen on this build.

Still very excited and I've glued body wood together. I'll need to start a thread on this build so folks can see your amazing 90s in place.

Here is a shot of Prototype #1. The freshly-wound prototype is on the left, propped-up with a Shatten/StewMac magnet tester. Note the shape and depth of the pickup bobbin. These bobbins are hard to get the wire off of if you make a mistake or break one. They are particularly deep and easy to break. I recommend using an Xacto knife to cut the wire off. Be careful. This bobbin came from another P-90 I broke and I stripped the wire and used it to prototype Dane's pickups. I hooked this one up to four-conductor wire to get check the resistance with one of my multimeters. Before I wind the final pickup, I'll install the screws and get some magnets going to check measurements. This is the part you don't get paid for...the R&D is actually the fun part! Getting the right wire pattern on the bobbin makes a huge difference in the sound. Next step -- install the metal on the pickup and make sure we are ready to go final. More to follow, John Attachments:

So I'm confused.... How are you getting a 4 wire conductor on what looks like a single coil? Do you run two wires at the same time? Or are you splitting 3 coils off? So that you get 3 coils on each side to split. I have only seen 4 wire on humbucker type pickups.

The inner coil sounds like the single-coil and when I add the outer coil, it sounds like a P-90. John

So are the two shielded from one another? Or are they wound one top of each other ... the outside wire laying on top of the other with nothing in between them?

I separate the winds - I use a product from the aerospace industry...a trade secret.

Wire on the coils..time to wire them up. P-90s have a lot of wire on them and they take a while to wind. Make sure you keep track of the start and end of the wire! John Attachments:

I know you wont say, but I know that duct tape is used a lot in aerospace. LOL Just messing with you.

How do we know for sure??? Hum I mean once a pickup is alive and working... who is going to take it apart? LOL! HA! HA! HA!

Bill Lawrence went as far as encasing his pups in resin so you couldnt peek inside.

Chris - he didn't publish the "K resistance" numbers on his pickups, either. I had several conversations with Mr. Lawrence over the years and he did a lot of unique things with his pickups!
I have one of his original Mt. Juliet, TN XL 500 pickup and it is probably the hottest humbucker I've ever played!

Wasn't it Bill Lawrence that Fender turned to when Joe Barden pickups ceased to become available for the Danny Gatton signature Telecaster? If so then that's surely praise for Mr. Lawrence? (Not that his capabilities were ever in question of course.)
