The owner said he installed this Nashville bridge when his original ABR-1 collapsed. Note the saddles have only reference slots. Work is required here...
My preference is a slot 1/2 the strings' diameter deep. I set all guitars up like this...
Thanks, Man...in all honesty, it needs to have all the frets pulled and the fretboard planed to remove the "humps" in the surface, but the owner wanted to retain the original frets, so this was the best I could do with those restrictions imposed.
