The harness was a great upgrade for my bass and contributes to a great sound.
However, I would just point out that while installing vintage pickups with slightly thicker stranded wires, it was not very easy to insert them into the holes of the solderless adapter. I’m not entirely sure they won’t come loose. With thinner wires, there will certainly be no issue.
But despite that difficulty, it is undoubtedly a high-quality product.
All I needed to do was drill out the pick guard to 3/8" and they fit perfectly. The kit included enough extra nuts and washer to get the shafts the right height. The solderless connection system was intuitive, easy to use, and made very tight connections. I know how to solder, but this really saves time and eliminates the possibility of making costly errors. Would do do this again should I have to.
Glad I bought them, as the ones from my Squier P-Bass were too small. These slipped on perfectly and I tightened the set screws to indicate level.
Excellent product
