I got my first bass, höfner ignition last winter. it sounded great and played well..now, after the winter when I tried to play, most strings make noise touching the first frets, even when I play a free note and also playing the strings on the first frets makes this ugly noise when they rattle against the frets..I suspect that the air humidity is now higher and the bass has somehow deformed because of this. The situation has now been like this all time, already 4 weeks.. So how to fix this?!
