Could this amp be the end all of metal amps past and present?I've played many and owned a few but have never heard any of them produce such clear brutal gain.Is there an amp that rivals the III in metal at the same price you can land one of these?I play metal and this amp produces the sound I hear in my head when I think of metal and I'd like to know of other amps that are in the same tone class and volume as the Mark III so I have future reference to bullshit amps and the real deal.
