My bass was suffering from pretty bad back bow for a couple of weeks. I took it in to a local shop on Saturday, where it was diagnosed, repaired, and I went on my way. It sounded great all across the fretboard. I picked it up today and the G string is already getting close enough to the first fret to affect the sound of an open note. I haven't even been playing excessively. Is the bass just a dog, or am I doing something to cause this? It's an ESP LTD B-155DX, and when not being played it sits on a stand in my room. The weather hasn't been particularly humid lately, though it is sometimes.
