Fishman Fluence bridge with passive neck pickup?

I'd like to do this. The obvious issue is the need for 25k and 250k pots. Would I be able to hack this by using a resitor in parallel with the switch?
 
It is possible. You need a 250k volume control. Active pickup should in theory be ok with higher pots values. However, I suggest to add a 30k fixed resistor as an additional load from the output of the active pickup to ground.

Problems I can see:
1). The active pickup may have a high output voltage and not really balance.
2) the pickups won’t combine very well in middle position. It is probably dominated by the active pickup.
3) Passive tone control will only be effective with the neck pickup. It is really hard to integrate one tone control to work on both types.

So in summary: you are really making things complicated and there will be compromises. Don’t expect this to be easy.

I tried mixing passives and actives before when I used an EMG SPC to buffer the signal from the passives. I wasn't happy with the result I achieved with the particular pickups. It was a Dimarzio Cruiser DP186 neck and EMG 89 bridge. I intend to make a second attempt with different pickups after I finish my current projects.
