Hello everyone,

I am new to the forum.

I must admit that I was referred through mylespaul.com to the link https://fretsnet.ning.com/forum/topics/doubleneck-wiring.

Have been playing the Hawaiian Steel Guitar since 1974. Only now I felt I should change my instrument so I got one made through a luthier in Kolkata India.

It's a double neck console style Hawaiian steel guitar, with each neck having two Seymour Duncan '59 Model humbuckers (B & N), one Seymour Duncan YJM Volume pot and one SD Tone pot. Two toggle switches have been incorporated and the circuit is designed around the Gibson EDS-1275 double neck model. All procurement decisions were taken in discussion with Seymour Duncan technical department and local luthiers. 

Short list of BOQ procured after long discussion with SD technical department:

1. Two of Seymour Duncan ‘59 Model Bridge Pickups
2. Two of Seymour Duncan ‘59 Model Neck Pickups
3. Two of Seymour Duncan YJM volume control pots 500K (logarithmic / audio taper)
4. Two of Seymour Duncan tone control pots 500K (linear)
5. One of Switchcraft 12010X switch - Long 3-way Neck selector switch
6. One of Switchcraft 12015X switch - 3-way Pickup Selector
7. One Switchcraft phono socket

It was only yesterday that I flew 1600 km from New Delhi to Kolkata to take delivery. Disaster struck when the guy told me he could not figure out the schematics and circuitry that I provided him, and therefore he couldn't get one of the toggle switches to work, while the other (the main one, 12015X) he could only configure for neck switching. 

As things stand now, no pickup switching, and God knows what else he's done, so the whole thing is a mess.

I have decided not to troubleshoot, rather to take apart the whole thing carefully and start afresh. For this purpose, I will need a fresh set of drawings, because the schematics I have (similar to the ones in that link above), do not provide connection details. Most confusing for me is the pickup selector switch configuration and I have no way to find out which is terminal 1, and which is what. A little help is sought to figure out these initial details.

I read the reply of Paul Young of May, 1 2013. Obviously, he seems to be an expert, while I am not. And the post is so old, I am not sure if he is still on this forum.

Any help in helping me figure out the terminals, the connectivity and the scheme will help complete the rewiring. Photos of the 12015X switch and the guitar are attached.

Also a switch setup diagram that I picked up along the way, is attached, not knowing if it is valid for my application.
