I use various. The earlier ones were hand created in some serif program I think, very slow going. I’ve used a few different ones but not sure I could remember them all. More recent stuff is done with Guitar Pro and Neck Diagrams. Point me to a specific page and I’ll probably be able to tell you what was used.
Thank you for your reply. I’ll definitely check out Guitar Pro and Neck Diagrams when I get a chance.
If you look at the Arpeggio page(s), the diagrams used are what I’m looking for. As opposed to the diagrams on the Scale page(s), the Arpeggio Page(s) have the degrees listed (1, 3, 5, 7, etc), this is what I’m looking for.

The arpeggio pages are done with Neck Diagrams. It’s a bit ‘clunky’ in design but does the job well enough and it’s fairly cheap. http://www.neckdiagrams.com
