Certainly as good a quality as the stock one installed on my Jazzmaster - which no longer works properly. Good idea to take a photo of soldering before installing as the are six connections. Works great now. I really like turning the volume down on the rhythm circuit and use this as a cut switch.
I bought four of these for a Squier Bass VI I upgraded. I was hoping to buy Fender branded switches, but couldn't find them and ordered these instead. Very happy with them. I think it's the same brand that came in the guitar stock, actually. Quality seems great...they have taken lots of heat from my less than stellar soldering, lots of initial wiring changes due to pickup configuration troubleshooting, and they all still work. That says a lot!
