Right now my bass is tuned to C-Standard but I'm using standard .045 - .105 gauge strings. Needless to say they are pretty loose and make a lot of noise. I've been looking into getting some thicker strings but I'm not sure how thick I should go. I don't want to get standard five string .130's as I don't feel like having to sand now the nut so they would fit (I play a 4-string Schecter Stiletto). I'd like to try out .110's but I have a feeling that they won't make that much of a difference as far as tension goes. Does anybody have any suggestions? Will .110's or maybe even .120's help or should I take my bass into a shop and see if they can adjust it so I can keep the .105's? Also, I know some people will say; "Get a five string if you are going to play in a low tuning", but I just can't play them very well. I don't like the strings being so close together or the thicker necks.
