I am considering a three pick up configuration for a custom build bass. I will be using two EMG 35 TW pickups from a previous build as well as a BTC control from around 2008. I used an 18 volt set up in this build and will use it in the new bass as well. For the third pickup (as a mud bucker) I will use either a CS or another TW pickup. My question concerns the wiring of this configuration. Would I have issues if I added another volume pot to control the third pick up or would I need to have a Strat type pickup selector? Instead of a Strat type set up would individual on off mini toggles be an option to turn an unused pickup off or is this even necessary if the volume pot is turned off? What would be the best way to wire this set up? I appreciate any input on this issue.
