Where to begin ? Here's a very rough time line with my opinion. My 75' precision is very good and cool. I've delved deeper into Fender P's - older years but with all due respect they don't sound any better to me. Mine is as much the real thing as I'll want. So then Leo left Fender (what year was it?) and worked on some Music Man basses right ? I don't like them even though I have played them and tried to like them. Are they the real thing? Yes and no. Yet, they are very high quality. Then Leo did the G&L gig. I suppose these are a culmination of some of Leo's previous designs. These are the basses I like the most. I have 2 (that I've modified extensively) and they far surpass my 75' in many ways. My 75' just sits there for history now - respectfully. Are G&L basses are the real thing ? Yes and no. Was Leo still designing basses when he died ? I'm glad that mine were both made at the original factory in Fullerton, Ca. There's some bones for us to chew on here at TB.
