I have a few basses in different tunings, with different gauges. For example, my standard tuned basses normally will be with strung with 40-100's and my full step down basses strung with 50-110's. I set these basses up with these gauges in mind, but even though some of these basses will be downtuned for an extended period, I still deem the tunings temporary, and I leave the nut alone. Now, there aren't any major problems with the nuts on my basses, but my latest acquisition, a MIM standard jaguar tuned down a full step has a nut that I think could be filed a little more, (for height, not width) at least on the E (D) and A (G) strings. The thing is, should I do this if I plan to go back to regular gauges and tunings someday? The reason for my question is that in watching some videos, it's recommended that I file for the gauge of string used. (so this will mean using a .110 file on a groove that is currently a .105). Won't that create a problem whenever I go back to standard? Will I just need a new nut when that time comes? Advice please.
