So I've been thinking of an idea for a project bass I can work on in long term to get essentially a more versatile bass. I'm not sure how much of this is feasible so if anyone has tried this or knows for sure whether or not this would work please let me know. P.S. There won't be any diagrams in my description as I am not super familiar with the whole diagram reading thing (part of why I mentioned "long term", as most of that time would be learning how to do it). This is for the chrome covered active-passive jaguar bass, not the standard mim like what they make now. A reverse-position SD quarter pound p-bass pickup in the middle/neck position, and a custom SD quarter pound version of the old fender blacktop p bass humbuckers with four wires for different options. Instead of the standard master volume and master tone/treble cut passive controls, I plan to install two concentric stacked knobs with a separate volume and tone (treble cut) for each, as this is what I prefer in general. The active treble roller pot control would be a mid control instead. Instead of the pickup selector switches, they would be rewired to function as follows: a three-way replacement for north coil, south coil and series humbucking options; a phase switch (just in case I decide that I want that sound at some point), and a kill switch for both ease in turning off the volume without changing how the pickups are balanced (and also for effect like what you could hear in something meant to sound more digitized and distorted). The active/passive switch would stay the same. Thank you to anyone who takes the time to read this. Any advice would be greatly appreciated.
