## Questions & Answers

**Q: Is there a wiring diagram for active pickups?**
A: There is no wiring diagram.  It is pretty simple for active pickups or non-active.   There are 3 wires that attach to the "blend" pot for the pickups.  I call it "blend" because there are 5 pots, V, B, M, T, and the "blend".  V=volume, B=bass, M=middle, T=treble.  "Blend" would be tone, but T is already labeled.   Battery is there, and a input jack.  I had to cut and solder the battery connector because my bass has a special compartment for the battery.  You will need to solder the pickup wires, all 3.   The 3 wires to the "blend" pot are for 1) neck PU (P1) 2) bridge PU (P2) and 3) ground/common.  There is a bridge hardware ground (common) spare wire as well so you don't get shocked.  You can see that spare wire in one of the photos, its a bare wire with black insulation.

**Q: Can you hook this up to passive bass pickups as a powered boost?**
A: Yes, as my review said, when the pots for frequency adjustment are un the center position, it boosts the original volume of your pickup without coloring your tone

**Q: Thinking of installing this into my custom p bass. any recommendations ???**
A: Swap the separated bass/treble pots for a concentric 100k pot. Also, if your p bqss also has just 1 pickup, remove the balance knob and change the volume knob for a push/pull 500k... so you can change passive / active

**Q: Where do i connect the pickups?**
A: The blend pot has connections labeled "P1" and "P2" where you'll connect the pickups' hot wires. There's also a connection labeled "GND" where you'll connect both ground or negative connections.
