Same here Bill.... I grab one of my Bass's and go to my happy place. The one where I'm single and 17 again..... 8)
What year and manufacturer is your P-Bass? Mine is a `92 American made California Special. It has Seymor Duncan 1/4 pounder pick-up's, Gotah high-mass bridge, and a Hip-Shot detuner. I think I'd sell my `Cuda before I let this Bass go. I told my Wife to bury me with the Damn thing!
All the others are negotiable..... :-D
