Hey, I have a Fender MIA Jazz which has become my main axe as of late. The problem is the neck profile is so damn thick that it hurts especially when I get to the song in our set where I'm slapping octaves. I love everything else about the bass. I also have a fretless MIM jazz which I use for a couple songs. And the thinner profile just feels so much better. I’m thinking about the possibility of putting of putting a MIM neck on my MIA. I would have liked an MIA one but it looks like they only sell the "modern c shape". Does anyone see a problem with that changing the neck? Is it a drastic downgrade?
