Hey everyone. Hopefully my title says it all I'm primarily a hard rock to crushing metal player. I'm going to be in the market soon for an ultra high gain amp, has to be musical, has to be machine like tight capable, and has to clean up nicely. So far I've tried a class ab/hybrid Blackstar HT50 head thru matching 4x12. I loved it!!!! It does everything I want in an amp, although I was only with it for 45 minutes at a music store. Loved it though. Then there's you typical JCM 900 or DSL 50 on Craigslist in the same price range, not to mention some new Jet City offerings. Then, for $549 there's the new Diamond Amps Assassin. Single channel, class a, 18 watts (rates max at 26), and all hand wired on a turret board. Birch cabs. This amp is "sexier" to me on paper, from a quality and reliability stand point. BUT in the end I can't buy amp that doesn't work totally for me this time around. Again, I like regular classic rock, hard rock, up to machine head, anthrax, fear factory, prong, slipknot types of tight metal. I understand that boosts, od pedals, and noise gates may need to be used. Overall, could an 18-26 watt class a high gain single channel amp be made to work for modern metal? Thanks, any info/input is appreciated.
