I've been playing bass for about 3 years now, and I currently play a MIA Jazz bass in our school's jazz band and our pep band, but I'm still playing on my starter Dean bass at home, and would like an upgrade. My current choices are: A used MIM Precision bass, the store owners assure me it plays well and there aren't any flaws other than cosmetic ones. A Squier Vintage Modified Jaguar bass for about the same price new, I've played one of these at the local guitar center and I loved the way it plays, but am I losing tone with the P/J duncan designed pickups compared to the MIM? And finally, an Ibanez SR400, I like the lightness of this bass but I don't know if you can get the punchy lows and the mids of the P Bass with the active pickups. I play in a three piece blues-rock band with my friends, and I would like a tone that's very heavy but cuts through the mix because our music is very bass-oriented thankfully. Thanks for any help, this is my first post so I'm sorry if this is the wrong place to ask this.
