For one song on TGE, Loomis uses drop Ab (or G# whichever you may call it)
I figured it was a 7 string tuned half a step down...cause the record didn't quite sound standard B tuning but it didn't sound like A tuning either.
I always thought Burn My Eyes - Machine Head was in Drop C and D standard. Maybe it's all over the place with those two tunings and also drop B and C standard
