I put a new set of strings on my X7 just now, *(Martin PB 13-56 mediums).
I had noticed previously that the neck looked like it had a bit more forward bow than it really needed.
When I tuned up it seemed more noticeable than before (heavier strings ? More critical eye ?)
Anyhoo ... got the provided truss rod key out and found that there was NO tension whatsoever on the rod.
Took a half turn or more just to bite, then I went in little increments about another half turn.
Action is sooo much better now ! Board is flatter and it is easier to play up the neck , no buzzing.
I was going to sand the saddle a bit, but I think that teeny turn of the screw has improved the playability enough now.
*I put these strings on pretty much everything from GS Mini to resonators to dreads, cheaper by the multi-pack, always sound good to me.
EDIT: Just read this back and I realise it’s guitar maintenance 101 to all you ol’ timers,
but I hope it might help another youngster like myself.....
