Usual top quality of CTS Pots & Switchcraft Jack plus Orange drops caps, like you found on American instruments, complete with wiring set. Wiring diagram is different than the one provided by seymour duncan. (I use the diagram from seymour duncan, also identical as the original squier).
I use it to Upgrade my Squier Jazz Bass CV 60s & Affinity PJ Bass. Need to modify the holes on my Bass to accommodate ¼ inch CTS Pots. Result is excellent. Pots are smother and lighter than standard squier one. Sounds subjectively better (just my opinion, maybe just placebo). Don’t forget to buy the knob that accepts ¼ inch or 6,35 mm shaft diameter.
