Notice
If you can play Stellar, then the main double-stop riff of this song should come pretty easily.
About the solo. It sounds like its either harp harmonics or some oriental instrument. For simplicity's sake, I just tabbed it out in harp harmonics. The left hand frets the note and the right hand both picks and lightly touches the string twelve frets above the fretted note to produce a harmonic an octave above.
Here what I think it really might be.....
Mike Einziger on Eric Johnson's Japanese Koto Technique:
Guitar World April 2001
"Some of the more unusual chord voicings I use actually come from listening to Eric Johnson and Steve Morse. We're recording a new album now, and I have a whole 'koto' thing worked out that comes from listening to Eric."
Here are some explanations for this technique I found on the Net....
1st Explanation
That's basically a two-handed fretboard technique.
You fret a note with your left hand, and at the same time use
your right-hand 1st finger to fret a note near it on the same string.
You use your right-hand 1st finger to fret a note near it on the
same string. The idea is to pluck the note as close to where you're
fretting as possible. Therefore, you get a very tinny, thin,
koto-like sound; you don't pick way back by the pickups where it's
fuller sounding. As I pluck the string, I use my left hand to vibrato
the note. So the 1st finger on the right hand frets behind the note
and adds vibrato.
2nd Explanation
I used something that Eric refers to as his ‘Koto’ technique.
This involves fretting the first note on every string with the
right hand index finger and using the thumb to pluck the string
just behind where you’re freting it. This results in a very thin
sound reminiscent of the aforementioned 17th century Japanese instrument.To complete the effect, pull off the right hand index finger to a note being fretted by the left hand (usually with the third finger) and as you dop that, bend the string very quickly up and down.
