My Mexican Jazz is... ok. New pickups improved the sound a lot but the neck and bridge are what let it down. I'm sure a Badass would be great but i'm not spending £50 on a bridge !
The neck is a bit of a pain, action has to be quite high to ensure a buzz free high end, low end isn't so bad. A previous owner had also stripped the truss rod nut but I've managed to sort that out and ajust the neck. Might get some heavier strings.. might make life easier.
Even though i've slagged it off - I'm glad I have it, it has that great old school sound to it and I imagine, these problems are nothing compared to how some Fenders have been.
