    I decided to spend this time in lockdown rehabbing and modding a guitar - I bought a used 2013 Gibson SG on this site and:
    • Reinstalled the original pickups
    • Added a middle, single coil pickup
    • Installed a Bigsby
    • Took the finish off the back of the neck
    • Cleaned and set up the guitar
    It went from this…

    ...to this.

    It was a fun project, and the middle pickup is very usable both on its own and blended with the humbuckers. The guitar plays great. I am not 100% sold on the Bigsby though - maybe I'll uninstall it. I also think I was a little heavy handed relic-ing the neck.

    More photos of the process are here: https://photos.app.goo.gl/ZPChnF3sEYBJT38r7

    Thanks for reading, please let men know if you have any questions. I'd like to do another one so I posted a WTB ad for a "project guitar" - https://www.thegearpage.net/board/index.php?threads/project-guitar.2151492/

    Great job! There are options to adjust the Bigsby - less stiff springs, and a different arm, as used by Chet Atkins, which is smaller and less clumsy to use (perhaps). I like the look of the big arm personally.

    Tell us more about the wiring of the added middle pickup?

    How is the middle wired in? I didn't grasp it from the linked photos.

    Needs a pickguard. All those 24 fret specials look so much better with one.

    Pretty cool project! Has me thinking this would be fun to do, especially to maybe play with different finishes.

    Here's what I did:
    • Three way switch for the humbuckers (neck/both/bridge)->
    • Output of three way switch and output of single coil -> a blend pot
    • Output of blend pot -> master volume
    • One tone for the humbuckers, one for the single coil
    That way when the blend pot is set to 10 (humbuckers) it behaves like a standard SG (three way switch, etc.) but with a single volume and tone.

    These are the controls:

    This is the wiring diagram:

    Any suggestions?

    Aha. From the photos it isn't clear that the blend pot is double-ganged.
    Are the two sections log and reverse-log, or is it linear?

    You could add tapering resistors but be aware that at when the blend is turned all the way to one side or the other, it will load the pickup or pickups like the guitar has a lower-resistance volume pot.

    I found the blend pot to be quite ineffective, in that it was mostly useful in only three positions (100%, 50%, 100%). So I replaced it with a 5 way rotary switch, so now the flow is:
    • 5 way switch for humbuckers (Neck, Neck-coiltap, Both, Bridge-ct, Bridge)* ->
    • 3 way switch for switching between single coil, humbuckers and both ->
    • Volume
    • (and separate tones for humbuckers and single coil)
    Next I'll add a phase switch for the middle pickup, but after that it's done. There are a lot of sounds in this guitar right now.

    *I initially wanted to use the PRS wiring but the 4 pole rotary switch from StewMac is too deep to fit into an SG so I removed the bottom layer.

    If anyone wants a used blend pot for the price of postage, please let me know. Even better if you want to trade if for a DPDT mini-toggle switch :)

    Center-on, center-off of two-position only?

    I do have a two-position DPDT toggle handy but it's not the micro size. It's approximately the size of a pickup selector. Would you be able to use it?
