His very first bend then at 0:29 are the more prominent ones to my ear. I really believe it is more a function of how well dressed your frets are, thats why I picked your Jr and tele as the best candidates. My SG does it only on the better frets I have.
As you bend a note, you are raising its pitch, naturally compressing the sound, so a clean smooth bend should get swell and get 'louder' as you approach the target note, then taper off. Barring rifts in your fingerboard for the string to get caught and lose momentum and energy, and imperfections on your frets (like wear ruts on some of mine) I don't see why most if not all guitars that are loud acoustically can not do this.
Can you give me a video time marker? I gotta be honest - I don't hear anything remarkable. So either all of my guitars do "that", or I'm a Phillistine.
Plus, how can you say "no vibrato" (or other finger effect) when you're playing as smoothly and expressively as he is?
