I took a trip recently (almost two weeks long) and when I came back my instrument felt completely different. During the trip I did play with a band and we rented basses in both cities that we played in. Could I still be "playing the other bass?" Has anyone expierienced something like this before? I've heard of instruments "opening up" is it possible for them to "close up" too? By the way, I've had the bass for about a year and have been extremely pleased with it until about two days ago. It has pretty much been my dream instrument until now. Thanks for any responce in advance.
