I have a Bill Lawrence P-46 and J-45 to install in my American Precision Deluxe. I've been debating about the best way to do it. I think I want to just remove the preamp with the old pickups. I sort of like having it, but I also like the idea of a simple, passive circuit with just two knobs and a switch (or a blend knob.) Most of my gigs are with a vintage-sounding swingy throwback band, but I also play in an emo-revival band with some pop-punky parts. Would you keep the active circuit with the 4 knob look or replace the pre-amp and go with something a bit more classic/classier. Also, does anyone know where to find a pickguard for a 2012 American Precision Deluxe with only 3 knob holes?
