I am looking at a Alvarez acoustic RB-30SC. It is in new condition except for a "crack in the finish". The crack is at is in the bridge area and extends along the grain under about under the E string. It LOOKS surficial. What are the chances that this is more than a finish issue. The fact that it runs straight up underneath the bridge to where the E-string peg is makes me leary. I can get it for about $150, which would be cheap for this bass, but I do not want to buy a broken bass.
