I've got a 2000 Mexican P-Bass and I love it, but it needs a bit more boom. I was looking to converting it to Billy's "Wife" but with a small mod. I want both outputs, but I want a push/pull pot to put both outputs to a single jack when out, seperate when in or vice versa. That's not the hard part. So the controls are P-Volume, Woofer-Volume, P-Tone. Also, I'm currently using an EMG P-Pickup. Will the output of the woofer be drowned by the active pickup?
