A while back in a local music shop, the bloke who sits around all day playing slap bass (who are these people who do this? why do they do it? where do they come from?) told me about boiling strings. Apparently, throwing them in a pan with some white vinegar cleans all the gunk off them, and makes them sound as good as new. Can anybody tell me whether this is true, or if the slap man is a bass solo short of a Level 42 song?
