Hello, How bad would it be to tune a 5-string bass EADGB? Would there be any out of tune notes? Would there be anything noticable? How bad would it be to tune a 6-string bass EADGBE? Again, same questions...? Well, you probably guessed I'm a guitarist. I'm studying jazz guitar at college and since I already know my arpeggios and all the notes on the neck, why not pick up a third instrument and add two strings I'm already familiar with? No one else would notice exept me, right?
