So far so good, it can do everything from dirty blues like ZZ Top to heavy rock, I don't really think its a metal amp but when boosted its got a lot of gain and sustain. It's one of those amps that will almost feedback even with cleaner settings. The amp is very quiet, hardly any hum even with gain close to dimed. I will try to take a vid doing VH type riffs or Lynch as I don't know much GnR, sorry was never a big fan of theirs although I do appreciate Slash's playing. I've played the latest Marshall Slash amp and the Ze can definitely get that 80's rock tone. Think everything from AC/DC, Dokken, Cult, even Yngwie could be covered with it.
