    The p pup on my bass has way to much power compared to the j pup.
    Can I run a flex core preamp AND emg p/j x off of one 9v? Will that reduce "headroom" or is it not even possible

    Should I just take out all foam from the p? Lower a bunch?

    Should I put in a pot to limit the p pup?

    Can I add a resistor ?

    I'm pretty low if but I have a buddy who can help me...

    Open to all suggestions because right now its not sounding great..

    Hmm. The P being louder is pretty normal. It is a louder pickup. All my PJs have done that.

    Sure it's normal. But does it have to be?

    How much louder ? Is it possible a wire is not connected correctly ?

    Not so far. Its connected. Any truth to not grounding emg with a ground wire to the bridge? This one is grounded

    I didnt ground mine. Are this the quick connects or solder ones ? I kinda remember having one of my quick connects swapped and having low output on a pickup.

    Ya, you shouldn't need to ground them to the bridge, but that won't make a difference in output. It's the nature of output by the bridge to be lower just because there's not as much vibration and low end energy going on back there. I no longer have a PJX set, but when I tried them, tapping on them seemed to yield similar volumes, so I think it's more a function of placement than anything.

    What is the reason for not needing to ground the emg?

    They have their own internal ground.
