I just purchased a CV Jazzmaster. I wanted to get something that I could learn to work on (adjust the truss rod, dress the frets, set the intonation and action, etc.) without worrying about ruining an expensive guitar. So here's my question: Is there any reason why I wouldn't want to sink money into this thing? What I'm thinking about is, over time, swapping out the pickups and electronics, replacing the bridge with a Mastery bridge, and eventually maybe even replacing the neck with an American Professional Jazzmaster neck. What would be left from the original guitar would be the body and maybe the vibrato (secondary question - any reason to consider replacing the vibrato with an American Professional, as well?). I'm not really worried about resale value (I understand how I might lose money if I ever eventually sold it on eBay or something). I'm just curious to hear opinions on why I wouldn't want to do this. The reasons why I would: 1) it spreads the costs over time, so I don't have to come up with $1500 upfront for an American Professional (I'm a lefty, so the market for quality used guitars is scant); and 2) I've already got this body, and I don't need two Jazzmasters. Happy holidays, everyone. I'm looking forward to reading your opinions.
