I did my re-wire last night. holy hooch, I really suck at soldering! Also I learned a valuable lesson about using solid core wire instead of stranded.... never again. everything went reasonably well though. I accidentally wired my tone pot switch upside down, and I also have a short somewhere that keeps grounding the bridge pickup, so I have to vigorously knock the tone knob to and from the 0 position. I'll fix both of those things tonight or saturday.
It wasn't complicated for me to execute at all. detach series joint, solder extension wire, solder to on/on switch, wire on/on switch to tone switch, wire tone switch to blade selector, and move the pole the ground was on, and rinse/repeat for other pickup. I still want to make a wiring diagram because this is something that high school me would have been apt to do and he needed wiring diagrams (edit: just realized this comment is ironic in the responses of a post where I'm asking for diagrams. I ended up not needing to reference one while doing the wiring, it was in my head LOL). When I do I'll post it here.
It is awesome. Having the coil split activated with a toggle switch feels way better, and being able to use the neck single coil right under the octave harmonic is amazing. There's definitely a tonal difference between the outers/inners. Thanks for your help! :headbang:
