Wow! I'm so glad I found this site! I just bought this guitar knowing that the guts had to be replaced. I kept the 3 single coils but replaced everything else. My problem is with the mid-tone control. The only thing it will do is kill the volume totally when I turn it all the way back. It does this in all switch positions. I have several standard strat diagrams that I have used in the past and I've checked my wiring a dozen times. Thinking it might be the pot, I replaced it with the same result. I even tried a different switch - nothing seems to make the pot work! Any suggestions would be much appreciated. Thanks!
Could be a bad capacitor. Normally, turning the tone pot down cuts out high frequencies only, as the cap lets high frequencies pass to ground, but blocks low frequencies. If the cap is busted, it might be letting all frequencies go to ground, making the tone control act like a volume.
I'm afraid I've screwed up in my analysis. So sorry! Here's what happens:
The Mid-Tone pot affects all switch positions except pos. 1 + 5
The Neck-Tone has no effect on pos. 3, 4 + 5
With the Neck-Tone rolled back, it kills all sound in pos. 1+2 Also with Neck-Tone rolled back, if I roll back the Mid-Tone, the sound returns in all positions except pos 5 and the sound has no treble whatsoever.
As you suggested, I've checked for a short in the tone circuit and to the output but can find none. A short would be an exposed hot touching ground?
The problem has been resolved. I had wired the neck p/u where the bridge p/u should have been on the switch. I corrected that and flipped the switch around and everything works great. Thanks for the suggestions.
It's slap-in-the-face obvious now... The bridge pickup generates more high frequencies and less lows, so the tone control would act more like a volume in these positions. Turning the middle tone control down would allow some of the lower frequencies to bleed through from the middle pickup (I think)
