There are a lot of wiring harnesses for sale out there with vintage this and vintage that and it plays up to the idea that old or vintage things are better. Is that the case? I’m not sure…
The owner of this guitar wanted to upgrade their guitar with a new wiring harness featuring CTS pots, a Switchcraft toggle switch and jack, Paper in Oil caps all wired up with braided wire to the 50s layout. I love “50s wiring” and use it on my own guitars, I like the way the volume works when the guitar is turned down. I also rate Switchcraft switches and other parts. As to whether PIO caps are better than any other type I’m note sure, hopefully this imropves the guitar the way the owner hoped.
