Go for the DR High Beams as Bubinga says. And get rid of the foam!! Once you stick on these, expensive but worth it strings, your sound will be transformed.
I can only echo what has been said, P basses genrally sound kack on their own but wind it up in a live scenario and they will cut through the mix, as they say. I have tried almost every knid of bass, active and passive but keep going back to the P. I have Status Half Rounds on mine and like the sound I get.
But, mabye the sound aint for you. If you are happy with the Schecter sound, why not stick with it and keep the P as a back up or move it on?
