I wanted to upgrade the pickups and the electronics on my Ibanez RX170 and I chose to go with EMG pickups. I could've used the original pickup selector that came with the guitar, but I didn't like the flimsy plasticy feel of it so I decided to go with the EMG switch.
Installing the switch was a breeze apart from the fact that the switch was slightly too large for the cavity, but with some desperation and brute force I was able to lug it in place.
Build quality is excellent and the switch operates just as I had hoped. Would definitely recommend and would buy again in a similar situation. The ease of installing the switch is well worth the money which isn't much more expensive than getting a conventional 5 way switch from an established brand.
All in all I'm very happy with the product, the only caveat being that the switch might be slightly larger than the one you're replacing it with, so be mindful of the size of the control cavity!
