I have an early 70's Gibson SG Pro that I just got that I've posted on before. The guitar has P90's in it and I'm getting a very weak, out of phase (quacky) kind of sound out of the middle position of the toggle switch. I have checked my guitars wiring and it appears to be ok. The pickup wire is braided ground so I cant swap ground and hot around to see if the problem goes away. What could be the problem? I've got the standard Gibson wiring shown here. http://guitarelectronics.zoovy.com/product/WDUHH3T2202 I'm not sure if its just the way the original pickups sound or not. I checked the pickups themselves as someone suggested the magnets may be not "in" properly. I cant see how you'd take the magnets out so I dont think thats the problem. I'll include a link to a bad pic of the back of one of the pickups. http://users.goldengate.net/~jgermann/pickup.JPG any ideas?
