I own a Savage 120 through Engl 4x12 Greenbacks.
Pros: It sounds massive, super versatile. and very tone-shapeing, though the Invader 100 beats it (i prefer Invader 100 over the 150)
The amp, how i set it, bleeds a dark high gain attack. Ihsahn from Emperor / Ihsashn uses a Savage 120 in his home studio, where late Emperor and all Ihsahn albums were recorded. The amp is very clear, but expect it to sound a little bit evil lol play with the contour, depth punch, and rough settings for the gain, so many sounds unbelievable. The cleans too are briliant and completely clear and warm, i like the "bright" setting for the clean Ch1. Ch2. is a little dirty-er, the amount of dirty up to you. Ch.3 is a more traditional high gain amp, but waaaay warmer than most. Ch.4 Is a lead blast to hell, put the first gain stage at about 12 o'clock and second at around 3 o'clock, harmonically rich gain soaked but still refined tone. Best amp I've owned personally. Floyd Rose + Savage 120 Lead Channel = hours of marvelous entertainment. :dimesquealsfromhell:
Beast of an amp.
Cons: lil bit heavy, but, pff, live in cases exist so whatever lol
