Well I just Got my Carvin B2000 Head This Week here....And WOW What a Beast!! I love how Just strait forward it is No Frills just raw power and man at 13 lbs it is a pleasure to pack around!Really like the Tube Pre Amp it adds just that lil bit of warmth and Growl...not alot just the right amount... I really dig the sound like it a bit better then my GK 1001rb II had a bit more warmth and clarity!! I Used it last For The first time at a Gospel Concert Where my Band Opened For Ron Kenoly ...In Fact His Bass player played through it as Well since there was some mess up in their gear ...And man She Is Clean and Powerful. I was running through my SWR 810(Still Waiting for my fEARfuls To Get here in a couple of weeks) And it was impressive...Every One Was Commenting on How clean And loud it was...my Band mates Really liked!! Cant Wait to Plug it into my fEARful 1515/66/1 and 15/6/1 into it....I better Make Sure my house is covered For Earthquake Damage The B2000 Is the Bomb!!!
