Hey guys
acoustic noob here.
Was fiddling around on a mate's acoustic - a custom job done by a local luthier (Italy) - and noticed that there was plenty of buzzing going on between the V and VII frets. He was pretty unfazed, just took out his hex key and set the neck nice and true again.
But here's the point.
His comment was "oh it happens all the time, especially when the weather changes".
It his normal? I mean for a neck to move that much?
