I've always wonder about this. I have been in bands for years, play with many bassists, played myself as well. I am mainly a guitarist but i love bass. One thing i've always been puzzled by is this certain type of ratteling sound i hear from bass. I dont know if its because people are sliding or because it's just because the thick strings are vibrating against the neck wood that it causes this sound. I've heard this on cheaper basses a lot more so than on higher ups. Yet when i listen to the radio say for instance Culture Clubs "do you really want to hurt me" (random i know) that bass line is just what i like to call "Bass Tones/Frequencies" it's not rattling strings it engulfs you, its just low tones without all the buzzing. Here is an example of what i am talking about. ! You can really hear the rattling/buzzing at around 1:22 and at other parts of the video. So what's up with all this? Is that done on purpose, and how does one stop getting a rattling sound and get more of just low bass tones? Thank you!!
