HaHa...
. 4 posts in and that's EXACTLY what I was going to post. I own both, and I own both because I wanted the most versatile bass and amp possible. I also went through a ton of other gear to get there, including a Warwick Jazzman, active Fenders, a custom bass, and a long line of others. I only mention those because my intent in buying them was to have as much versatility as possible.
The Carvin head I didn't buy because of it's versatility. I bought it because of it's size and price, and then found only afterward found out what kind of monster that thing is. You can mold and shape your sound with that head much more than with any other amp I ever owned. It became my one and only (outside of my backup).
That being said, and you being a young player I have something to add. Versatility is a great thing, but also comes with it's troubles. My amp I'm happy with because I set and forget it... but versatile basses I only recently realized can make me unhappy at times. I played active basses for over 20 years and only recently started playing passive basses. What I've found is this. All the passive basses I own sound great in any mix, no matter what I do with the knobs. All neck, all bridge, a mix of either - my basses cut, sit well in the mix, and everyone is happy. It's not quite like that with a bass that can sound like anything from the dubbiest upright to a banjo. While you may be able to get precisely what you're looking for in tone, because of the differences in rooms and stages, you're never going to really get the same sound twice. It's great that you can get 1000 sounds out of a bass, but only 100 of those are going to sound great. That leaves 900 that aren't going sit in the mix quite as well. I used to have the head to tweak and get exactly what I was looking for, but I'm finding myself a lot happier these days with basses that can't fail. I have 4 passive basses now I use all the time - a Carprice, a Ric, a Gibson EB (2013), and a Jazz. I can get those basses to sound like just about anything, and they always sound good. My more versatile basses take a a hell of a lot more work.
Not saying versatility is a bad thing. Only that it comes with a price.
