so a tune o matic bridge.
All I play are Les Pauls :)

It might be the saddle slidey thing* that the string is sitting on at the bridge, the string might have cut down a little deep into it.

Either that or the nut has been cut down a bit by string movement, which is unlikely, but can still happen.
I'd get it taken to a pro if it's a Gibson, you have to treat them well - and if someone's set it up really nicely, they're a wet dream to play.

*the slidey thing, y'know. Official terminology.

Thanks :D
Appreciate the advice as it's my second but I much prefer this one, I'm giving the first to my father.
This one is a lot easier to play with my sausage hands so I want to keep some of the action but remove the fret buzz!

no problemo
if they're set up nicely and the tune o matic is correct across all the strings, they're awesome bits of kit.
