I'm really confused. Aren't the diagrams provided that of the Cmaj Pentonic scale? For example, the notes of Box 1 on the fifth fret are A-C-D-E-G-A... That makes it 6-1-2-3-5-6... Even Torvund's example is in the key of A, how is that fingering 1-b3-4-5-b7, instead of 1-3-4-5-7?

TIA

The C major and A minor pentatonics use the same notes.

When you use numbers to indicate scale steps, you're using the major scale for comparison. A major = A-B-C#-D-E-F#-G#-A, so A pentatonic (A-C-D-E-G) = 1-b3-4-5-b7

Why is it A minor and not C major? I realize they use the same notes, but why the different name this time? I guess it sounds stupid, but isn't it really just playing a Cmaj pent over an Amaj progression?

What I mean is... A 12-bar blues in A uses (perhaps) A-D7-E7. That means I'm playing AEACEA (1-5-1-3-5-1) and DACFAD (1-5-b7-3-5-1) for the Amaj and D7 chords. So why is it called A and not C?

It depends on the context. The Am pentatonic scale starts on an A, the C major on a C. You could play C major instead of Am but the feel would be different.

Ah, a pot-ay-to, pot-ah-to thing is it then?

Not quite. More like bow and bow (he took a bow after tying the bow)

Same notes (letters), different sound because of context.

There are a lot of scales that have identical notes - C major and F Lydian, for instance. The difference is in the root tone - that's the tonal center of your melody. Change the tonal center, you change the way melodies resolve... so you change the name of the scale for clarity.
