I dont use one myself at the moment, but I'm considering it, for no other reason than to add to my tone/sound. I've read on some bass forums that plectrum players are considered somehow inferior by "real" (there's that word again ) bassists. This would not put me off using one, as I consider it a load of s***e. If it suits the music, then what is the problem ? The legendary bassist Carol Kaye always uses one, and if it she is not a "real" bassist than I don't know who is.
I'm just curious if there is the same bias here towards bassists who use a pick.
