they do. otherwise thered be no point in going to art school or learning to paint ... theres the same techniques used over and over and over and over and over and over ...
and sam, i understand what youre saying and ive been the same. but with age comes knowledge imo - and reusing sounds is FAAAAR from bad or anything else. and someday you will get over your own shadow and just do it - and you know why? because it just makes more sense. this one day you WILL have the tune which will only sound good with that bass you used in your last tune - and you will do it. from then on your point of view will be different.
and you will have learned A LOT till that day, so just do whatever you like and become good at that
