I'd been keeping an eye out locally for a used Jazz Bass as I've never owned a jazz and am curious to try one.
I picked up a Korean Squier a week ago for AU$200 (~US$130). Serial number indicates it's out of the Samick factory in 1991.
Advertised in good condition, but partly disassembled because the owner had got tired of trying to work out why there was hum & buzzing. After checking that all parts were present and there was no damage, I took it off his hands.
A few hours work over the long weekend and it's now singing very nicely.
Issues were:
- Open circuit neck pickup. Coil wire broken near the eyelet solder terminal. Fixed by unwrapping the last winding and reterminating in the eyelet as per original termination.
- Bridge pickup couldn't be adjusted to correct height. Foam underneath had compressed, so an extra piece had been added, making it way too high. Removed both pieces and replaced with fresh material.
- Tone control was intermittent due to a loose terminal on the pot. Repaired & refitted the pot. Cleaned & lubricated all pots & O/P jack.
- The quality of the wiring & soldering was terrible thanks to the owners tinkering, so I removed the wiring and a lot of excess solder & flux and completely redid it.
- The serrated eyelet terminal & wire for connecting the conductive paint in the cavities to the output jack ground was not fitted.
I suspect that just one these issues came up originally and the rest were most likely caused by the lack of knowledge and skill employed in the repair attempt!
Put it all back together, set the pickup heights and gave it a run.
No hum or noise, and playing very nicely overall, but still a mechanical buzz whenever the A or E string was plucked. The buzz went away whenever I touched the A tuner and turned out the button was loose on that tuner. The quality of the "Licensed by Schaller" tuners looks quite good, and no issues with any of the others, so that tuner might have been knocked against something solid at some time. Fixed it with a tiny quantity of RapidFix.
So, for AU$200 and a few hours of my time, I now have a what appears to be a very decent Jazz Bass. It's early days, but I do like the feel and love the versatility already.
