I have decided to add a Jazz bridge pickup to my Squier Precision. I'm a great one for research which is what brought me to this forum. In my cyber travels I found a template and router bits on Stewmac, how to shield and ground everything etc etc, but I also found something which really caught my interest... concentric (stacked) 250/500k pots. In my mind I thought it would be possible to stay with the existing 3 holes - volume, treble, jack - of the precision, but by using concentric pots, have a separate volume and tone control for each pickup. I don't want to clutter up the bass with any switches, but I would like to be able to isolate each pickup just by turning the volume down on the other one, or dialling them up separately to get a blend for certain songs. I've searched the forum but can't find a definitive answer on whether this is possible. For example, would one pair of pots need to act as volumes and one pair for tones, or would the individual stacked pairs have to act as a volume/tone for each separate pickup? hope the wording of my question is not too ambiguous. I've been all over the internet searching for diagrams but nothing seems to cover using stacked concentric pots in this way. I am keen to take photos and make comments as the project progresses from routing to shielding to wiring and so forth, because I think the concept visually has very tidy looking potential not to mention the improvement in frequency control. I should add that electronics is not my forte but as they say have soldering iron will travel.
