    That there is a whole world of interesting. they've put shielding tape around the coils obviously in an attempt to reduce hum... wouldja mind taking a multimeter to the coils... I'd be interested to see what they spec out at... I'd bet good money they're pretty unbalanced...

    FYI, I've done exactly as you've done above with slanting the coilsand it's worked out just fine for me. Technically you'd want to repot the pickup after your done but you'll likely be okay.... baseplate looks like painted brass.. easy to source from your local Metalsupermarket or similar....

    Oh yeah, I did that for my first 9 string 2" fan fret build, totally works. Dude from elysian suggested I ground out my pole pieces as well, so another usefull tool while you have the base plate off...If you dont give a shilt like me, have deep enough pickup routes, and your anxoius try things out, make the base plate out of wood and cover it with that copper tape...totally works..

    I decided to try and replicate the original baseplate as best that I could, so I modelled a sheetmetal and tried to fabricate it out of 1mm brass. I could have had it water jet cut before folding, but couldn’t wait for the operator to come back to work so I made the part by hand. A few photos below.

    Now I need to paint it black, solder the ground wires and re-install the side tapes and hope it still works.

    Finished the pickup. The paintjob is ghetto, and re-used all the original side tapes. Also took a multimeter and checked that everything grounds ok, total measured coil resistance was 15,78 kohms, specified 15,90 kohms so close enough. The separate coils measured 7,92 kohms and 7,88 kohms respectively.

    Also my Hipshot products arrived finally so now I can accurately place all the mounting holes to the body and neck 3D-models.

    How did the diagonalizing affect your string spacing? The strings/poles being too close together is the thing that has kept me looking at (n+1)-sized, bar/(2n-1) pick-ups for multi-scaled guitars.

    It's been a while, I've been busy honeymooning with my freshly acquired EBMM JP7. Still, I've slowly made some progress with the 3D-model - re-shaping the body and headstock. I've also started to shape the controls-cavity to my liking. Tone, Volume and a 3-way switch. Either tone or volume pot will be push-pull for coil-tapping. The jack positioning is also still up for debate. I've decided to go for a bottom adjusting truss-rod, and since I haven't found a perfect one commercially, I'm seriously considering making one from scratch. A couple of teasers:

    That looks lovely! Is it the truss rod not reaching to the nut on baritone heel wheel setups that's the issue for you? Have you seen the Fast Guitars / Tao Guitars solution? Just an idea
