Hey hey hey! Matamp GT200 mk2 the glorious is here!
Its big and heavy as hell, which is pretty unusuall for the most of the bass gear.
I took a shot with Orange OR120 head for size reference.
Got interal fan, quad of KT88 , 200watts nominal and no DI, thumbs up if you dont care about DI output in tube bass amp
I would say that this bass head steps on guitar's amp territory, got enough highs and gain.
