I tried installing a middle strat pup in my tele. I wired it to the tone pot......changing the tone pot to a separate volume to blend the new pup in. The hot wire from the pup goes to one of the outer terminals and the middle terminal is attached to the output. The idea is to have the usual 3 tele settings and to be able to blend the middle pup in if desired. It works, but when it's turned right down there is still some sound from the new pickup. It won't turn completely off. I tried connecting the 3rd terminal to ground, as on the diagrams (Brent Mason mod on the S. Duncan site), but that just made it a master volume for all 3 pups. I have no idea what is hapenning. Can anyone help, or do I have to access the new pup with an on/off switch to turn the bugger right off?
