My first thought is try using the same brand of strings you used before, if that solves the problem then there you have it. Try that first.
I agree! š The reason is that even with identical guages (thicknesses) the core material’s relative elasticity/tension can be just different enough so as to alter the overall tension-to-pitch! This might be the equivalent to using the same exact guage, but then setting up your guitar tuned a “quarter-step” flat for example! This could have the effect of pulling the bridge down closer to the body, thus lowering the action and causing that dreaded “fret-buzz.” Arrrgggh!!! š”
BOTTOM LINE: Try the SAME manufacturer/brand AND same guage strings first. Then, check your bridge’s relative proximity to the body (if you can remember or have some close-up pictures from recently!) Then finally, (if that doesn’t solve the issue) do as someone else here had mentioned and check your individual string heights, and perhaps any other pertinent “guitar-setup” parameters/procedures (like truss-rod/neck-relief; (overall) bridge-height adjustment, (individual) string-saddle-height adjustment; etc.) You might want to review the most excellent and comprehensive Guitar Setup Tutorial by Richard Lundmark here at Infinite Guitar!
