Just wondering as I use it for 6 string guitar and it's great for showing scales and chords / triads with notes or intervals labelled.

I'm guessing there maybe limitations for psg but the creator might well be open to suggestions to make it more useful to pedal steelers, if there was enough interest to warrant it.

Matt, I do not use that software. After watching some Joe Wright tuition videos where he used one, I created my own neck charts that I use from time to time when I'm trying to improve my theory knowledge. You still have to figure how charts 'change' with your copedant but I find it helps. My charts are on my web site steel pages.

Matt - Buddy Emmons used some in the articles (and other places) he did for the Steel Guitarist magazine (1980's). Here's the link.

This is great. No - I don't mean the chart thing. What I mean is I have just discovered the Buddy Emmons site and also Allan Kelly's site. Brill. Now all I need is the time to study it all if the wife stops finding me jobs to do.
