I have a Fujiyama FB-10L - I realize it is not a high end unit but it was very inexpensive when I bought almost two years ago and had no issues then. I am not a bass player first, so it spends considerable time 'resting' in between plays. The last time I played it was in the fall of last year where I used it extensively to record an album, and it was fine then too. Now the G string has major buzz...I can play it open or the first position only and even then you can tell something isn't right. Every other position is unplayable. The instrument is stored upright in a home made stand out of the sun and has never been inadvertently smacked or whacked. I have not detuned it when it is standing there and it does get pretty dry here (Calgary AB - REALLY dry actually)...so I'm wondering if these two things have something to do with it. The other strings seem to be fine. Any thoughts on what has caused this to happen?
