If you want a tone control on the middle pickup, you either move the neck-pickup tone control to the middle position or run an extra wire to one of the tone pots so you'll have a tone control active on every pickup.
Actually, if that's what you want, you can just run a 1 inch jumper from one lug to the other making them both active for the tone control. Most of mine are with the middle and bridge on the same tone control. I just jumped the two together. Took 10 minutes.
TIP: Instead of pulling all the strings off, I have a piece of broom handle about 6 inches long. I just loosen the strings on a strat enough to slip that under them at about the 19th or 20th fret, and that is out of the way enough to get the guard off.
fwiw I like the middle pup without a tone control it sounds killer like that and it helps articulate the in-between positions better...
I have a couple like this and a couple with it tied to the bridge. I "think" next time I am under the hood, I'll put them all like this. The more I think about it, the more sense it makes to me. I rarely use the middle pup alone anyway, and when I have, I never rolled back the tone, so..
Ain't that the truth. That's how I have mine setup - no tone on the middle pickup at all. It really does help the split positions brighten up.fwiw I like the middle pup without a tone control it sounds killer like that and it helps articulate the in-between positions better...
