Ok so I play in drop C and I'm upgrading my strings since there is still a bit of looseness (is that a word?) and flaws when playing. I'm using ernie balls 110 heavy bottoms. I was thinking of upgrading to a 125 or 130, so I have to ask do the strings have to fit exactly into the nut.....since it will be tight regardless? I'm expecting a large increase not to fit so I'd also like to know how much sanding down the nut would cost me? In case I do have to get it done. thanks all!
When I tuned down to drop c I used a five-string set. No nut adjustment necessary, oddly enough.
