Here's a rambling rant: So, I've pretty much played Jazz basses the entire time I've played bass (about 15 years). I recently acquired a P bass around Christmas. I played it a for a few days with the rounds it came with, and then put on a 6 month old set of chromes. It's a 2008 American Standard P. Ive never owned a MIA bass before, and it feels much better than my MIM Jazz or my Squier CV Jazz. I ventured into the P with flats world thanks in big part to a lot of the posts here. So far, I can say that the tone I'm getting out of this bass is very close to being my favorite bass tone. It's almost a cliche around here, but it does really fit well in the mix. That being said, the Jazz guy in me keeps popping up and saying that if I got a 'nice' jazz bass, I'd probably like it just as much. I don't know why, but I have this internal struggle where I have to decide definitively which one I prefer, even though I own both. I need to categorize myself for some reason. Tonewise, I definitely am very much into the vintage vibe. I'm not much for 5 strings, or active basses, or slapping. I think it's safe to say that I'm probably a lifetime flatwounds convert as well. All of these factors, at least in my mind, put me more in the P bass camp. Also, this is probably blasphemous, but I really don't care for Jaco's style. I respect his talent, but it really irks me that anytime a Jazz bass is mentioned, especially the back pickup, his name gets mentioned. So...I'm either a P bass guy or an against the grain Jazz guy. Probably the #1 reason I would lean back to the Jazz is that I am ultimately on the quest to own only 1 bass. I'd feel comfortable brining a jazz bass into almost any situation. The P bass, while perfect for some styles, might not be as versatile. Anyway, I'm starting to get GAS now for an AVRI jazz with flats. It never ends!
