Strung it up yesterday with the crappies and tried out all the different switch positions and lo and behold they all work! So I'm happy with my wiring. The pots themselves are not that great; volume on each pickup achieves not very much until about the last 10% of turn; equally the tone on each doesn't really alter until almost turned right down. So the electronics are really just OK and nothing special. Strangely, each neck plays well until you get up to the first fret (under the nut) when it doesn't play well at all. Have to take a closer look at the set up for an SG and make sure the clearances are as they should be. Again, with grandee birthday parties etc I need them back at school to devote more time to my project!!
