I killed it with my Mark III, I nailed that 80s metal sound perfectly, cause the other guitarist in my band has one, but then he can't change his sound to a newer metal tone or much else. I am happy.
My Mark III '87 Purple stripe, rackmount but in a rack all to itself.
Needs new power tubes, not because they are old, but because I don't like them.
Love it so much ;_;
