I have a 50's Classic Precision with GHS flats that I love. Lately though I find myself playing mostly on the E and A strings. I just like the tone a lot better on those two stings. On Sunday I played and American Standard Jazz and with both volume pots dimed and the tone was rich and full on all the stings. I tried all the other Jazz basses in the store and to my ears that is the one that had the tone I like. I hated the tone on Jazz 5 string, and the MIM standard and MIM 60's classic didn't have it either. So, I started wondering what would it sound like if I put some good rounds on my Precision? So what do you think, change the strings on the P or try and find a used American Standard Jazz and hope it matches the tone of the one I played. If I get a used one I will probably have to buy it online, no luck on Craigslist yet. One way saves a lot of money, the other way is risky but if I get a good Jazz I feel like I will have the best of both worlds. Plus I'm not even sure if rounds on my P-bass will do the trick.
