I've had this bass for 7 years now and feel its time to change things up a bit. I would like to swap out the pick ups and the on board pre-amp. I do know that I would to swap out the E string machine to the hipshot d tuner because I'm constantly switch the top string pending what I am playing. Any thoughts/advice or suggestions I am open too. Also does anyone know anything about doing some sort to vinyl wrap to pick guards. Mine has aged so much that its gone from white to a really dirty cream color... Thanks in advance for your help and thoughts.
