Fender Squier Musicmaster circuit issue.

[NikNik]

I'm currently doing some work on one of these. It's the Vista series. I decided to fit a standard P-bass circuit but I have noticed that there is a considerable loss of volume when the tone is off. Also, there's also still some top end there when tone rolled right off.

The original circuit was butchered so unsure what the factory version is. Am I needing a resistor/cap somewhere? My soldering is ok, as are the two caps I used.

Ahhh....I've just discovered it's a guitar pickup!!

 

Nope, it's not. Not on this model. Baffled.
