    I'm in the process of converting my Casady bass to a lefty. I made a lefty bone nut and reversed the strings, reset the bridge and strung it up so it's playable. While I had the strings off I pulled the pickup to get a look under. I noticed that the pickup doesn't look "symmetrical"- there's a metal bar on the treble end and the electrical connections on the other. When I replaced the pickup I flipped it, figuring that it might have "a bass end and a treble end".

    Anyone know any more about the construction of the pickup? Is it "asymmetrical"?

    Next step is to drill the holes and flip the electronics, plug the old holes and smooth them over. Refinish will have to wait until warmer weather- spraying nitro in the closed up garage isn't going to work.

    I also noticed the interesting construction of the center bar. It's solid under the neck and under the bridge, but routed down 90% the rest of the way. A thin layer against the back in between. It really is a hybrid semi/hollow-body.

    Anyone have a good photo of their bridge? I'd like to get a look at the height and angle/rake of your set-up.

    I'm curious too. This is probably the modern day "Mystery Pickup" (ala the old Ampeg Scroll pickup ) because the pickup as well as the bass are totally unique creatures unto themselves.

    No idea, but from what I've read, the pickup was the one thing about his original Gibson that Jack insisted needed to be replaced for the signature model. Don't know where the new pickup came from, if I recall, it has "Electrar" on the front.

    Finally got going on my lefty conversion. I pulled the electronics, looks to be just like the schematic. One pot has 2.5 stamped on it, the other is stamped 500 but has 2.5 printed on it? The volume pot has the "treble bleed" gizmo and both of the caps are "mustard blob" tantalum as per the schematic. Holes drilled and old ones plugged, skimmed with Bondo, lefty bone nut fabricated.

    You must have worked in the repair department of CME in the old days. ;)

    A lot of people don't know how good of a repair material Bondo is for any kind of wood repair that will have a solid finish. I learned about it from a finish carpenter who was installing a curved staircase in a house I was framing. He put up the curved skirt boards on the second floor in glued layers and slicked all the seams with bondo, finish sanded and it was beauty-ous after paint. When you think about it, Bondo is as high end of a filler/patch you can get for a painted finish, as opposed to wood fillers which are homeowner grade rubbish, only good for nail holes, basically.
    I mean, it has its limitations, nobody is going to cast a body out of it or use it in place of wood or a proper adhesive where that is needed, but within reasonable bounds it can't be beat.

    It is certainly a lot quicker than making proper wood plugs for the holes, I'll give you that. :)

    He did say he plugged and skimmed it...pretty much my gist too.:)

    Easy there big fella. Plugged the holes with tapered maple plugs (widgetco.com) and Titebond to match the maple top. Sanded flat, Bondo just to fill any cracks and seams. Couldn't do that if it was going to be a sunburst or natural top, but for a black finish it works just fine. Bondo sure beats the "plastic wood" stuff for this purpose.

    Sorry, I stand corrected. I saw "plugged, skimmed with Bondo" as just using Bondo, which is how Chicago Music Exchange used to do work on vintage instruments.

    I am sure you are doing a much better job of modifying the bass than Gibson/Epiphone would have done so. :)

    I bought some Minwax "High Performance Wood Filler" thinking "sounds high-tech"! Pried the cover off, smells just like...bondo. Doh! I just paid twice the going rate for wood dough colored .... bondo. Cool project BTW, looking forward to seeing the finished product. I always liked semi- hollows.

    Fully functional- and passable to look at. I'll have to wait for better weather to do the final finishing, but I've got a coat of paint (lacquer spray) over the old holes. WD made me a lefty pickguard. I have the new fingerboard side dot markers but they're not in yet. Woo Hoo!

    Great to see this unique JC bass in (more than less) finished shape. Why is the pickup mounted upside down? Not enough lead to keep it oriented correctly?

    Nice job, just wondering why you didn't fill that pickguard screw hole?

    See above in the thread. If you look at the bottom of the pickup its not symmetrical- there's a bar on one end. So I'm guessing that it's built that way for a reason (bass end-treble end?) and flipped it.

    "All good things in all good time"! I'll most likely refinish the whole top this summer and catch all that stuff then- it's actually still pretty rough over the filled old control holes. It's going to be a player, not a case queen. ;)

    The pickup appears to be "handed", non-symmetrical, treble and bass sides are different. When I first looked at the backside of one, I noticed the same thing.
