Thanks.. but I think I found a diagram for the T-45... I'd post it if I could figure out how to attach a file- but it sort of looks like the red coil tap lead is being sent to a second tone pot with a H6 inductor coil to ground that rolls off low freq's.
I got a tele in peices on my workbench, but when I'm done with that I'll start playing with the t-40.
my first thought is to wire both red leads to a common rolloff pot as I have only one inductor coil.... my second thought is to find another inductor coil and wire both pickups like seperate T-45 volume/tone/tone circuits, than wire them back to a standard 3way pickup selector.... more interesting to me the second way if I can find the right parts.
