Hello all! I'm new to this forum, as I am to the bass guitar. My first post is a problem/question right away, so here goes: I recently bought a Yamaha BBG5S 5-string. I think it was a good deal and I like it very much. There's only one thing: the E string seems to have a 'double' tone. I'm not sure how to explain it, but it sounds off key while it isn't. It's tuned correctly, but it seems to have a second underlying tone slightly off key. When the string is played open it's not that obvious, but when I push in at a position on the fretboard, it is audible. When I play unplugged, it's not that obvious either, although it seems like something in the bass is buzzing along. It's only with the E string, the rest is just fine. I tried fine tuning the saddle, but it doesn't make any difference. Different tunings don't matter either. Is this a common problem? Could it be the string itself that needs to be replaced or is something else going on? It's a used bass, so I hope I didn't buy a defect one. I hope anyone can help me out with this one. Any help is appreciated.
