Hey there Jemsite. Even though I am currently working on my repaint of one of my 540R's I bought some electronics for the next project I will be tackling once that is finished. I have a JS100 that I will be stripping down to bare wood... and I bought (on ebay) an AZ series HH switch assembly complete with the switch, voicing switch... POT's all wired together. My only issue is... Where to I solder the pickups lol? So in the picture you can see it plainly says Ground, cold, hot, cold, hot and then above that is some text referring to the pickup in which to solder. Seems pretty cut and dry. This is essentially for my reassurance of my thoughts, all my ground wires... (bare and green in this case) go to ground...? That's 4 wires going to that small terminal... Now I can solder them all together, heat shrink tube them... and run a single wire to that spot, that's not a problem. And then the hots and colds go to their specific locations. Take a look and let me know what you think. Also if there are any AZ owners reading this, if you could snap a picture of your HH config'd AZ switch I'd appreciate it.
