I'm at my wits end with a Gibson Nighthawk that I'm trying to eliminate buzz on all 3 wound strings.
After doing a full setup on this guitar, I noted pronounced buzz all over the neck, on the bass strings.
So, default fix number 1; I did a complete fret level and dress, after noting a few high fret areas.
Blown away ..... this did not cure the issue, I have never had buzz issues after doing a full fret level before!
It was fitted with 9 - 42's to start, so I tried changing the bass strings to 26, 36, 46, thinking maybe the floppy light strings were the problem. This did nothing as well.
Now, just to note, I tried major relief in the neck, less relief in the neck, raised the saddles, lowered the saddles, nothing stops this buzz.
I searched for a sympathetic buzz/rattle, stripping and analysing the bridge, stripping and checking the pickups and cavities, ensuring the height springs etc were snug, ensuring the machine heads were not the cause, checking the nut was secure, nut slot heights etc. NOTHING!
Any thoughts from our esteemed gurus would be appreciated ...
I have been doing guitar setups professionally for many many years, and this situation has me super frustrated.
