I noticed on the end of fulara'a guitars that he has some sort of cloth near the nut to obviously cancel unwanted sounded notes...it that something available for purchase?
I use a plecktrum mostly,but tap often...usually scales and even riffs(you can make some great riffs tapping)Ive never concieved a tune using tapping exclusivley though.Sounds like crud when I tap bass notes with my right hand and treble notes with my left(thats "potrato" technique right?)...

Later!
