Repeat final F#m chord sequence 6 times, then activate a
"holding-delay" and sample the chaotic noise to produce the wildness. Then
use pick slides and wah-wah. Deactivate the "held" delay. Activate a
regular delay and hold an E5 chord with pinky and ring finger at the 2nd
fret, then with the index finger, press the low E string down hard behind
the guitar s nut to produce the tremolo dive-bar sounds (or use tremolo),
all the while holding guitar facing or partially facing amp to create a semicontrollable feedback to finish the song.
