I neeed a new amp for bass and guitar

I'd recommend getting a Tech 21 rackmount preamp and whatever powerful power amp you want. Then try out different bass cabs to see what you like.

An svt will definitely be fantastic as is with guitar

Yeah. I play guitar through my mesas all the time.. and my bassman20…. and I run my orange and sunn through 15s… and use them for bass as much as guitar
