One of the reasons I have chosen an eight-string guitar as my main instrument is that I love having access to the extended pitch range and chord voicing possibilities offered by the additional two lower strings. I tune my eight-string, low to high, to E B E A D G B E. This way, my lowest string is an E, an octave below the sixth string, and the seventh string is B, as it normally is on a seven-string guitar.
The most obvious way to illuminate why this tuning is useful is by starting with a normal major barre chord.
