I recently purchased a used 2015 MIM Fender Precision Bass off of the GC used site for $349.99. The details listed for the bass listed that the bass included a case, High Mass Bridge, Bass Extender, and Seymour Duncan Quarter Pounder pickups. IMO opinion these were all desirable extras (except for the High Mass Bridge which I could go either way on). All the extras alone would have cost about $300, so I figured it was a pretty good deal. It was listed in good condition. The first day I play the bass at home through a Fender Rumble 500 head and I absolutely love it. The tone, the feel, the neck, the look, everything is perfect except for this occasional buzz or hum which surprised me because it is a Pbass. It didn't occur all the time, but was enough to be extremely annoying. I played two of my other basses using the same cable and amp with absolutely no buzz or hum. So it is definitely the bass. The second day I have it, I take it to band practice, and I again absolutely love everything about the bass except now being played at louder volumes the buzz/hum is worse and even more annoying. What do you guys think is causing this hum. My assumption would be that the pickups or bridge were not installed properly. Could it be an easy fix or is it not worth my time. Again I really like the bass. I would just take it back, but I really like the bass and I don't think I would have an easy time finding one at that price in this good of shape with all the extras. I am considering taking it back to GC and telling them I will keep it if they fix the hum, or I may even try to get it fixed on my own. Any thoughts or advice would be appreciated.
