I just added a CS NoCaster to my collection. It still has the early '50s wiring with the blend pot. I have considered leaving it as it is because I really, really like the blend.
However, I had a previous AmStd Tele wired with a blend in place of the tone pot. It was a pretty dark sounding guitar so I never used the tone pot anyway. It worked out extremely well.
That being said.......I think I may try the concentric pot on the NoCaster. I would use the "bottom" section for the blend and the "top" section for the tone.
Visiting the TDPri always causes me to spend money!
