I don't know how many Matamp fans are on this website but I just got this guy and wanted to show it off. It's the most articulate and clear amp I've ever played. The low end is incredible. It also sounds amazing for bass. The build quality is flawless and it's also the loudest amp I've ever played. It makes my other Matamp (GTL 140) not seem brutally loud. KT88s>EL34s. Before I got this the GTL was the loudest amp I've ever played. The GT 150 also takes pedals like a champ. Tl;dr Matamp good.
