I do NOT want this thread to become another "P vs J" thread that never ends! Yes, i have searched but i seem to suck at it and can't find a discussion about the subject. Anyway, this is a forum, can't hurt with more discussion. I want you all to discuss what the title says. What was Leo's thoughts behind the names? I think they makes no sense. Maybe the precision was about "a bass with frets = intonation made easy? Can't even guess how he came up with Jazz bass name..
