I just scored a Cort fretless acoustic bass for a bargain price. Part of the reason it was a bargain is because there is a crack in the top, about 8 inches long, parrallel to the strings and halfway between the bridge and the side of the body. The nut has also had the corner cracked off it on the E string. Anyway, the E string is very thudish compared with the other strings. I wondered if the frequency of the low E may be being affected by the crack more than the other strings causing the problem? Alternatively it may be just a very old set of strings? It certainly sounds more thuddy than a new version of the same bass I played a while ago so I don't think it's just a characteristic of the model. I don't know if I'll do anything about it if it turns out repairs cost more than it did as the bass was bought as an "office" beater and it's fine for that! Just wondering if anyone had any ideas?
