Okay, I answered my own questions but I'll put it on here in case anyone else had these problems. I checked my switch power supply and it looks like Gibson found the cheapest one they could for this beautiful guitar and it isn't producing any output. I'm sure I've used it about 3 times so I guess it died in the case. I have another on the way ($4.78) that will be the cheapest thing I have ever purchased for a Gibson guitar, ha! Now, the MCK or control knob, I'm old so I had to get out my magnifiers for this one. The knob has a set screw. I would guess it takes about a 1/32 allen wrench, somewhere between a .5mm and a 1mm. My first thought was that I would never be able to find one that size, then it struck me to look in the storage area in the case. Gibson included 2 in the plastic bag with the standard neck adjusting tool. Thanks guys, I guess one is an extra if you loose one, they are about 1 1/4" long, VERY TINY, so the knob is back on and the PW is on the way. I've found videos on the procedure for charging so I guess I'll be good to go. If PW works I'll order a couple of extras for standby. Sorry for the stupid questions but that's the way it goes sometime.
