Newbie new build pickup questions for HSS configuration.

This guy gives a good demo of the difference between 50s and modern style wiring . What he shows is the way old (and CS reissue) Gibsons are wired; there's other ways of doing it to achieve the same result (sometimes your controls won't be close enough together so the cap can bridge them).

His custom Jr style guitar is cool for having both switchable, pretty nifty.

Great video and description of 50's wiring -- so much to learn. Thanks for sharing it!
 
I'm gathering some supplies for soldering and wondering what diameter solder you guys find the most useful for this kind of work? I was thinking .o8mm so there is a bit of stiffness to it. I'm going with 60/40 Rosin core solder. Thoughts??
 
Kester 63/37 is the perfect eutectic blend. If you're ordering online, might as well go with "perfect."

Thanks for the link Artie! Questions...
What makes this blend 'perfect' for you?
Do you use .020mm diameter solder? This seems really thin to me.
Seymour Duncan tech videos recommend the 60/40. Is one blend easier to work with than the other?
Thanks!
 
The diameter isn't all that important. Get the size that best fits your application.

I've been a tech for over half a century. Mostly DOD, with the Army, Air Force, and then Navy. We got refresher courses on soldering biennially, and tested annually. 63/37 is when solder meets the perfect "plastic" state for flowing and adhesion. 60/40 is slightly cheaper, or lazy labeling. It would be ok for guitar work. We just wouldn't use it for a guidance system in an F-14 or a Peacekeeper missile. (Their name, not mine.)

OK I'm sold!! :-)
 
Thanks again to everyone for your help!

I'm going to copy the configuration of this Obsidian Wire HSS harness and would like to confirm some things. Will definitely need some wiring diagram and treble bleed help, etc. For now just trying to understand the bigger components.

This is a 250/250/500 pot set up. The humbucker will have a push/pull coil split on the tone knob. Is the master volume the 500k pot with circuitry to let the singles only see 250k? Or is the tone pot for humbucker the 500k pot? Assuming the middle tone pot is 250k for sure? (remember this is my first go at this stuff :-))

This set up auto splits the humbucker whenever the switch position pairs it with a single coil. Looks to only be position 2 on the diagram below.

And FYI - I'm not trying to have the HSH option switch shown on this harness.

Any thoughts, info and/or advice is very welcome...thanks again.
