Chord Solidbody Bass Upgrade and Makeover

Happy New Year folks :) This is my first post for 2021, and it features a "Chord" solidbody bass that looks a lot like a typical Jazz Bass. Construction-wise, this bass sports a plywood body, three-ply white/black/white pickguard, bolt-on maple neck; and 12" radius rosewood fretboard with 21 frets. The electronics consist of two single-coil pickups wired to two volumes and a master tone.

As the owner didn't quite like the stock red finish, he requested that the bass be refinished in flat black. He also wanted the "Chord" headstock label removed, for obvious reasons. And so, the headstock face was sanded down to bare wood; and refinished in Tru-Oil. Meanwhile, any visible dings and gouges in the body were filled with Elmer's Wood Filler and sanded flat. Then, after scuff-sanding the whole body, it was refinished in flat black; with a top coat of flat clear for added protection.

Although the stock electronics were working fine, I was instructed to upgrade them, and while I was at it; shield the body cavities with conductive shielding paint. New components added included Alpha 250K pots, a Russian K40Y-9 0.033uF tone cap; and Neutrik/Rean NYS229 output jack.

Hardware-wise, all rusty components were replaced. Luckily, the bridge, as well as control and neck plates; were still in useable condition. They were given a good de-gunking, lube and polish; and reused. The open-gear "elephant ear" tuners, however, just had to go. The gears were worn and would not turn smoothly even after servicing. One of them even had a loose ear which would not stay in place. As such, they were honorably discharged; and a new set installed. And, as expected; it was not a simple drop-in job. The old tuner mounting screw holes had to be plugged and trimmed flush, new holes drilled; and the tuner holes reamed a bit to accommodate the slightly-larger tuner posts.

Well, folks, that's it for this post. Thanks for visiting, and do drop by again soon. Meanwhile, stay home, stay safe; and God bless :)

1981 Ibanez Blazer BL-400: Part Three

Quick Links:    Part One | Part Two | Part Three | Part Four

In this third instalment on a droolicious Ibanez BL-400, let's take a look at what was done electronics-wise. Now, as the guitar was unshielded save for some foil underneath the pickguard; a full shielding was installed utilizing conductive shielding paint, aluminium foil and a grounding tab.

The wires emanating from the Super 6 pickups themselves looked a tad iffy. Seems like someone had taken a soldering iron to them somewhere along the line and left a sloppy mess of solder blobs, loosely-hanging leads and burnt insulation. The only remedy, then; would be to desolder, clean up the leads, and resolder them to the flatwork.

All the control cavity components were replaced, save for the Switchcraft #11 jack which was in immaculate shape. Nothing out of the ordinary: Alpha A500K pots, Gotoh DM-50 selector switch, NKK DPDT toggle switch; and Russian K40Y-7 0.033uF tone cap.
