Measure 30: Hand position is same as in measure 29 and the right hand fingering is exactly the same but you slowly slide the left hand fingers upwards while playing the right hand pattern.
Measures 35 etc.: 6,5,4 strings played in pizzicato, others not. Muted chords are muted with the left hand. GTR3 is percussion on the fretboard about the 19th fret with thumb. The chord of very high notes is playing with the left hand index finger behind the 0th fret, which produces high notes but without definite values, so it is just for midi playback.
Measure 37 and 39: "tremolo bar diving" is actually tuning the 1st string rapidly with the left hand one halftone down and then back.
Measure 49: Right hand fingering for the low melody is p-i-p-p - i-p-i-p - p-i-p-i - p-i-p-i.
If you want to play it ask me for sheet music and/or a recording, I couldn't put all indications in the tab and they are very important.
