Since these potentiometers have two separate resistance elements they are equivalent to a dual-gang potentiometer like a Fender® TBX® which has 2 potentiometers on one shaft (not the same as a dual concentric stack-knob potentiometer with 1 shaft inside the other). Here are some suggestions for wiring the dual elements:
- For redundancy try running jumpers to connect both elements together. This way if one element gets dirty the other one might not.
- You can hook 2 different pickups to one knob: one to each element with different tone caps. I like a .015 or .022uf for treble pickups and .05 or .1uf for neck pickups. Don't turn the .1uf tone all the way down, use it to just roll off a certain high frequency band that makes even a Telecaster® neck pickup sound like a jazz-box arch top
- If you have to isolate 2 pickups from each other and you are limited to one hole for a tone control you can wire one pickup to each wafer and only the grounds are common
Our custom Bourns PDB183 push/pull pot is a little different than your normal design because it features two sets of lugs on the stacked pot. You can use these as a volume or tone control for two pickups with one pot/knob. Plus you have the push-pull switch as well for splitting humbuckers, or a variety of other potentials needing two switches (DPDT).
