Lakland 55-02 active-passive swap

The volume pot on a Lakland 55-02 is: in for active, and pull out for passive.

I'd like to swap that so it's: in for PASSIVE, out for active.

Here's is the wiring diagram for the LH-3 preamp that is installed in my bass:

I don't have a problem doing this myself, I just need to know which wire(s) to swap.

Anyone???...or should this be in another forum?

It's actually very easy to do. Just change the wiring so that the jumper is on the end of the switch (away from the pot), and the green and yellow wires with the resistors are on the other end closest to the pot.

The switch contacts close opposite to the position the switch is in, so when it's pushed in, the green and yellow wires are connected together. The jumper is the bypass. You want to swap those two ends.
