I recently had a 4 way switch installed in my telecaster and asked the tech to make the 4th position both pickups in series. I also had a switch installed for out of phase sounds in the 2nd and 4th position. I was under the impression that the 4 position would sound a bit louder and a little more like a humbucker, but I got it back today have been a little disappointed. The volume seems to be the same as the other positions and it almost sounds like the regular 2nd positon with the tone rolled off to about half way. Is this normal or did the tech wire the switch incorrectly?
