Nice clear diagram, very easy to assemble and solder. I ordered this for a home-made Precision bass, I have used the Allparts J-Style wiring kit before and was very happy with the finished result. I was careful with not using up too much wire and was left with 4cm of the black and 10cm of the white wire at the end. I used Wilkinson alnico 5 pickups and EB Slinkys on this build and I am over the moon with the end result, it looks nice and tidy, the pots feel and sound smooth and the bass sounds fantastic, exactly as a new Fender Precision does. All in all a simple but excellent value wiring kit with good quality components... Does the job perfectly! :)
