Re: How often do you clean your bass?
If I just briefly take the bass out of the case and play it for a short time, I might skip it.
If I record a bass track in the summer and I'm sweating while playing (I tend to skimp on energy bills so I can have more gear money), then the bass is definitely going to get wiped after I'm done, and the strings will get wiped with one of those special string cleaner cloths.
Lately I've been putting coated strings on the basses too, because I figure as infrequently as I get around to playing any of my basses, I'm better off leaving a set of strings on it that I can use for a few years before putting new ones on.
