Could anyone suggest to me what may be wrong with my bass neck? It never quite seems to settle. The truss rod works fine, but it seems that every few days I need to adjust it. It seems to go both ways too, if I adjust it one way after a few days it will have to much relief. Adjust it back and a few days later not enough relief. It never bows to become unplayable, but it's enough for me to be unhappy with the action at its extremes. It's a relatively new (but out of warranty) Rockbass Streamer Nt1. Neck through, graphite reinforced etc. Any ideas folks?
