As an older player, I have been attached to playing my Birdsong Cortobass I had them build for me 8 years ago. As a matter of fact, I have sold off nearly all of my other basses, keeping my MIJ Fender P Bass from the 80's and a Mustang that stays at my drummer's house. Now that I have had my left shoulder replaced and back in good shape, I am thinking of buying a new Fender Pro American Jazz with a slim C neck. Any thoughts from those of you who have one, or those that don't, would be greatly appreciated. Thanks in advance.
