I have gibson j-45. New model with adjustable bridge. The saddle has a spring type mechanism underneath it that allows the string tension to govern the action, based on how the two adjustable screws are set (height).
When i change chords i get a bridge buzz, primarily caused by the release of the D and G string. Confirmed by muring those strings.
We have explored every setup adjustment. Neck, action, strings, humidity, nut and frets are perfect- been pleked. Its a new guitar, didnt buzz first 3 weeks after hours of playing.
I am convinced its cause is the mechanism of the adjustable bridge and the release of pressure upon chord changes.
My description does little to describe the mechanical nature of this design but seems to me a logical culprit
Anyone have any experience or advice to cure
