No, MissOhio, the actual design of the
slide rule is the same, but what it displays is different ... that is to say, the GfB&B slide rule displays well known chord shapes in a nice easy to use fashion. It uses several inserts to do that.
The
PT slide rule uses just one insert to display the lesson that the book/DVD teach. Since music is music and guitars are guitars, the PT information is also on those GfB&B inserts, but it might take you a long time to zero in on what that is.
