Do you know the width of its nut or the string spacing spec?

I'd fit, most probably a move down to lighter if not equivalent, at least 12-53 gauge strings so you are operating from a known datum. Even a single size segment shift lighter will make a significant difference without unduly upsetting bridge tension or nut slot fit. Fresh strings are also much nicer to fret, quite distinct from their 'day vs night' tonal advantage.

Also measure that your guitar's action is within spec. After, if you do change strings.
