Hello, I currently have the EMG P installed into my Fender Precision Bass. My question is if I install an LJ in the bridge position and a BTC System, could I decide not to use the volume, and just use the blend knob for switching between pickups, and the stacked bass/treble knob and it working properly. Basically I would just like to use 2 holes from the pickguard and the last one for the input. Would this setup work properly? Thanks. P.S: I had to stuff in the battery when I first installed my EMG P. Thanks for all your help.
