I've had this bass for pretty much ever (since the early 90's, anyway) It's a Korean-made (possibly by Cort) P-bass copy, pretty standard other than the Jazz bridge pup and being a neck-thru design. 3-piece maple neck, and "soft maple" wings added.
My first nice guitar was the same brand, they had standard bolt-neck basses and guitars like mine, and the "Professional" neck-thru ones for 3-4X what mine cost. WHen I found this bass at a pawn shop in Milwaukee it was a few years old and a LOT cheaper than when I had seen them as new. I didn't know anything about them until I got online a few years ago, so I didn't know about where it was from, the construction, etc. Anyway mine was stock until this week, it plays and sounds great (to me anyway) so I didn't want to mess with anything. I did step on the cord and break the guardplate years ago, but I just added extra screws to hold the piece on.
It has "Select by EMG" pups like a lot of low-mid import guitars from back then. The wooden parts, the tuners and bridge all seem good, but the electronics are all pretty cheap, though-mini pots and the "box style" pup switch.
Well about a year ago the selector switch got really loose, and I had to "wiggle" it to get sound to come out, and I wasn't sure it was actually doing anything when I did get sound. Also I found somewhere to get a black/red/black pickguard to replace the single-ply black one. I just liked it so much I was kinda hesitant to take it apart, since every time I start a project, it seems to never get finished...
So anyway I got my pickguard, a real 3-way lever switch and a couple pots. The routing in the body would barely fit a full-size pot in, let alone a bunch of wiring, so I ended up getting new mini pots. I debated enlarging the route (and going nuts and cutting a new output jack hole in the side, to avoid breaking the pickguard again) but chickened out and got minis and kept the top output.
THe wiring was kind of strange, it sounded fine for all these years until the switch broke. The capacitor was attatched to the output jack instead of one of the pots, never seen that before. I also didn't know that the pups were attatched to the body, so it kind of suprised me when I took the old guard off and everything stayed on the bass...
I just played it like that for a while, just because it was kinda strange.
