My fender active jazz bass does not "sustain" notes anymore. I tried changing the batteries, tried using a new cable, and adjusting amp settings, etc, however I think it might be the strings. About a week ago my roomate accidentally spilled a can of sprite on the bass (although I was able to clean it up). I was thinking that maybe the sprite stuck to the strings, maybe oxidized them or something. Is this the most likely cause, and do I just need to redo my strings? Hopefully it did not mess up anything electronically like the pickups.
