I've now fitted 500K pots to both the model P and the original MFD bridge pickup. I have to say that I like the model P better than the original MFD precision pickup, for the reasons I stated earlier. The model P also enables the bass to behave like a more "traditional" PJ bass. In particular, the 50:50 pickup mix tone is more balanced to my ears, as the bridge pickup is no longer overpowered by the MFD neck pickup.
It's not better or worse, just different, and I prefer it this way, for my tastes.
Anyway, heres a quick soundclip of the 3 main pickup positions in the new setup ..... 100% model P, 50:50 model P:MFD bridge and 100% MFD bridge. All again simply bass straight into my recording software.

My latest thoughts are that I really like this setup, but I would like to add a tone control. Think I might get a dual pot to give me that functionality, just to take some of the top end off the 50:50 setting. To be honest I would never use the bridge pickup only setting.
