I'm currently installing an OBP-3 in a new project bass with an active / passive switch (or actually, it's more a preamp bypass as the pickups are active EMG's). I'm following this diagram: https://www.bestbassgear.com/wiring-diagrams/v-bl-t--msw-b-ap-tone.pdf I would like to add a LED on the DPDT switch, as an indicator when the preamp is ON. Can someone told me how to do / or edit the current diagram ? I'm also planning to put a 6.8k resistor to reduce power consumption from the LED. Does this sounds good ? Thanks!
