Ok well i just played "hey man nice shot" on bass and it has a bunch of HOPO's. the chorus is all hopo's and even the other parts have a few hopos too. its not overly hard song either on expert bass, so thats a good one.
Also, the Metallica pack 1, those 3 songs are hard as balls but they have alot of hopo's in the solos if your good. i played on expert no fail mode and i got a few lol.
Isn't a signature your name. So techincally this should be where your name goes, yet no one ever does that....Interesting
