so i bought an sx p-j bass with the maple neck. i love the way it sounds, but i didn't realize that p-necks felt so different from j necks. i've played p's before, but never as much or as intensely as i do with my own instrument. so now, my playing feels a touch clumsier and my left wrist seems to get sore rather quickly. i'd like to get a j neck, but spending an addition hundred or more dollars on something i spent 130 on seems a bit excessive. why can i not find a used one anywhere on the internet?
