    One of the perks of doing what I do for a living is that I sometimes come across intresting stuff to trade for as payment for under-the-table work. Yesterday I picked up a plain black Junior, serial# SI9806XXXX as partial payment with cash. It's a little abused and has some wierd S*** going on: like the no-name HB hiding under the P90 cover, the tone control is MIA, and the wiring was a mess of electricians tape and slightly different gauges. On the other hand the body hasn't been moded(like taking a router to the pup cavity), only one small knick in the upper edge of the body, and the neck is much better than I would have expected for a plywood body Junior. So I took it as it looks like a good project for hot rodding.
    As far as electronics is concerned I have a box full of nos Alpha full sized pots, Sprague caps, cloth covered and shielded wiring, etc, so there's no issue for me to rebuild the wiring harness `50s style. On the other hand I'll need a P90 to fill the now empty cavity, nut(the current one is some kind of plastic, I thought that I might as well spring for a Tusq as I've always had good luck with them in the past), and maybe no-name tuners as the current ones have spots where they are hard to turn when you rotate them. I thought about shielding as well,...
    Sooo, if anyone has any ideas for the parts that I mentioned above, I'm ALL ears!
    And Thanks in advance!

    You got any pictures? We like those . It sounds like you have built a few guitars . On the pickups there are so many choices and on a single pickup Guitar .I see some are for neck some are for bridge it’s got to be a balance of both I guess.

    This was taken after I removed the birds nest wiring and the humbucker hiding beneath the P90 cover.

    This was the area of my biggest concern: that someone would have butchered the cavity in order to mount a different pup. Happily it's unmolested and I can mount a dog ear without too much trouble. I'm thinkin' now as well that I'll replace the pearloid PG with a plain black one,...

    Shielding looks good, did you line the pickup cavity and connect it to the control cavity as well?

    Getting there. If you want to touch up the paint, nail polish is the thing. There must be 50 shades of black, so better bring your guitar to the ladies department.

    Yup, did both cavities: one of the black wires that you see curing around at the lower left is from the pup cavity(the other is from the bridge post) and it's soldered to the control cavity shielding. It was a bit of a pain as the surface of the wood in there wasn't very smooth but in the end I managed to get it done with continuity all the way around.

    I kinda like it a little rough looking, it sorta reminds me of the way that they bashed up the team bus in the movie "Slapshot" to make the bus look meaner,...:D

    One thing about that Warman pup though, the resistance is a little higher than I would usually see in a P90, a touch more than 9K: I'm wondering what it will sound like when it's all up and running?

    Good job! You should have ground continuity from the tuners to the jack and everywhere in-between. I like to check shield to bridge as well just be sure everything that should be sent to ground is.

    From the guitars I've shielded, rough routs are pretty common across the brands and it it's not that it's gloppy cavity finishes. It's not supposed to be seen, so the labor time isn't invested. On my buddy's Mexican Strat they left tons of buffing compound in the cavities. I was in there with toothpicks and q-tips cleaning that schmoo out prior to shielding.

    Boy, I know what THAT is like. A coupla' years back I got an ash strat body from GFS that was loaded with the stuff. Took me two afternoons of working the same way you did to get all that gunk out. Turned out to be a good body in the end although it is a little on the heavy side: northern ash I guess as I've read that it is noticably heavier than swamp ash.

    Slowly gettin' there,..
    Put two bagged strings on to hold the bridge in place and I couldn't resist plugging it into my prectice amp. I have to say that for a cheapie pickup, the Warman P90 has some serious snarl even without a set up. And the shielding must have been effective as this is one of the most hum-less P90s that I've heard. I'm going to have to hunt down a body for a set of them now I think:

    Apologies for the crappy photo and my inability to set the date correctly.:D
    You'll notice though that my cat Ralph isn't much impressed(he's a Ibenez fan),...
