i had my guitar for almost a year now, an ibanez rgr321ex with a fixed bridge, ok here's the problem i detuned down my guitar to drop c the past month and it was still working fine, no fret buzzing anywhere but as the month passed by i recently had fret buzzes from my 1st to 5th fret, was that an effect of the dropping to drop c that now i have to adjust the truss rod, or need an neck adjustment? someone pls help me out on this one. thanks.
Your strings are gonna have more play when you detune, which would result in some fret buzzing. They was i always deal with it is raise the strings. But like you said, you have a fixed bridge.
I guess it could be the action. Also, if you tune that low, ernie ball super slinkies are good i hear.
