Hello All, After about 6 months of teaching myself how to play on a squier affinity P that I picked up in the pawn shop, I bought myself a brand new Fender MIM Jazz. At first this baby was the bass of my dreams, it was beautiful and had the tone that I had wanted. After about two months I figured it would be a good call to replace the factory strings, as they were losing a little bit of brightness that I like from rounds. So I picked up a pack of EB rounds and slapped em on. Immediately I got a lot of fret buzz(in the 2nd and 4th frets of the E and A strings), but I figured this could just be the new strings needing some time to settle in. After about a month I decided to ask the guy I was taking lessons from if this was normal or what, he said that it wasn't and that I should take it to a tech. So the next week I drove to the local guitar shop and got their tech to check her out. He worked on it for 5 days, each day saying that he couldn't eliminate the buzz. So he just suggested some new strings. I got him to put them on this time (I have changed strings on guitars and basses many times, but just figured maybe I had goofed up or something this time), a set of DR high-beams. They only made things worse. He took her for one more day and said that there could be possible fret work needed to fix the bass but put a heck of a lot of relief in the neck and raised the action quite a bit. Still being dissatisfied, I took the bass back to the guitar center where I had bought it and let one of their techs have a go with her. He took it for a week and said it was all fixed. Overjoyed, I drove to GC to pick it up, once I arrived I found the bass to have had borderline no work done to it, the buzz was arguably worse, and all he had done was lower the action. Frustrated, I asked that he take it back and I reiterated the issue and asked that he try again. So about two days later he calls again and says that the bass was all ready. I show up, and the buzz still remains. He tells me that "this is pretty normal for a bass, and that if I were to play any model they had on the wall I would find something similar". I asked if he could use the manufacturers warranty to send it off to Fender and maybe have them take a look, and his respond was simply "dude, there's nothing wrong". If anyone has some advice on what the issue could really be please comment and help a guy out, I'm sure it sounds like I'm being a bit picky with my bass, but I'm really not; the fret buzz is loud enough to be heard over a amp at medium volumes. Thanks for your time.
