Right now i am playing through a Katana mini.Am looking for a tight modern metal tone,usuaully am tuned A standard on my 7 and d standard on my six.I have a 2x12 cab I built with a swamp thang and governor.Should I get a katana head and be done?Is it really as good as the interweb says it is?Or should I go for something like a GE 200 with a poweramp or try an frfr cab.Budget is $500 to $700 CAD.Have been down the used route,looking to buy new.Opinions,suggestions,please
