Jed didn't like using 7 strings. He used the low G on LTD Eclipses. 24.75 inch scale and low G were a pain to tune and think of that guy's picking attack. He used .60 gauge for the low G, same with Dev, but he was playing on an LTD SC607B at 27 inch scale with a .60. Fear Factory used low G when Christian was on guitar too.
