Aloha. I'm new to electric guitars and to posting. I have been playing, collecting and making ukuleles. Just got a S65D Ser No. ED100452 by way of ebay. Internet searching states that this guitar has a coil tap switch. The pickguard has a puka for one but there is only a black disk in the hole. I could take it apart and look but I don't want to screw any thing up-everything works. Great, well made guitar with lots of sustain - something ukes don't have - will be learning a lot. Mahalo to all for the posts I have surfed here. Happy to learn from some fellow geezers. A hui hou.
