Could anyone tell me what's meant by Blues box? Is it the so-called B.B. King position, which as far as I know is based around the second inversion of a maj chord (e.g. in the key of A the notes g and a on the second string and c and on the first string) and where the King himself bends and vibrates the hell out of it as it just pleases him? As far as I understand Blues boxes are comfort zones within the pentatonic scale patterns, or am I wrong about that? Which are yours?
Hmmm...
