"musical training" is sometimes the worst thing you can do to a bass player. I spent 5 years in a big band learning to read Jazz charts after getting a degree in Music Education, that was tough, but what was tougher, was learning to play rock and funk again after "reading" jazz charts for so many years. I became fixated on the charts and forgot how to just close my eyes, listen and simply find the "groove". After a year back at it, I am finally coming around, still can't remember the licks for sh*t, so I make simple "cheat sheets", it works for now. I rediscovered my love of the bass though, when there aren't sooo many rules, and you can simply express yourself on this instrument...good luck bro. I know a few "noobs" that play better than I do because they aren't so bogged down with "knowledge". So don't let that get you down.
