Having plugged the new Jet JS400  guitar into the amp I noticed the string buzz which led me down the rabbit hole of truss rod adjustment to increase the neck relief.   Having watched a couple of videos I set about trying to achieve a 2mm gap at the 7^th fret of the 6^th string (low E) by adjusting the rod with a Capo on the first fret and holding down at the 17^th  (the body) fret and inserting a feeler gauge over the fret.  After a coupe of small adjustments the gap was set and when retuned the buzz had gone.


With this success in place I turned my attention to the PRS SE 245 where I needed to decrease the neck relief a little to bring it in line with PRS recommendations.

Perhaps I shall venture into action / intonation checking & adjustment soon too!
