After reading through the Precision/Jazz thread recently posted, I was surprised to find that most players who own both's go to sound lies in the P. I just bought one, put flats on it for that classic tone, and found, after years of J playing, that the predominantly low end sound is taking some getting used to. I'm interested to hear how other basser's tone have morphed over time. I started out with no treble, everyone used flats then, and the predominant bass sound was bass. To be honest, at that time I was far less confident in my playing, and found I could hide better in those low frequency reeds. After picking it up again in '96 I found that rounds were the string du jour, and that bassers were finding a more distinctive, personal tone. I found mine by turning the bridge pup up full (before only the neck) as well as the treble (before it was off). Amp pretty much 12:00 for bass/treble tones, midrange past that. What's your tonal history?
