I have 24 frets on my bass and your thing only goes up to 19...
Actually, it goes to 20. The reason it only has 20 frets is the same as the reason it only has 4 strings. Initially, I made it for my own personal use, and I play 4-string Fender jazzes
If you print it out on 2 8 1/2" x 11" sheets of paper, you end up with a little over an inch left on one sheet. Should be enough room to write in the missing notes
Seriously, though, when I get around to making 5 and 6 string versions, I'll take them all up to 24 frets, as well
