Last night I changed the strings on my Squier Vintage Modified Strat. I used a different brand but the same gauge (.009-.042) Prior to swapping out the strings I had no fret buzz.
Now, the 9th fret is dead, but only on the high E string. It buzzes at the 9th on the all the other strings, somewhat, but is completely dead on the high E.
I paid for a complete setup of this guitar a month or so ago. During the setup the frets
were dressed, etc.
Could the problem I’m experiencing be due to shoddy workmanship on the part of the
“luthier” who set up my guitar is it probably related to something else?
Thanks much.

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! 😉 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!!! 😡

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!
