They are small, light loud and yellow. What's there to dislike?
Back when I was shopping for a 412 full stack I'd have taken the MB version, but they did not have an 8 ohms 212 cab. Now that they do, I'm done shopping for cabs and settled on something else.
I've owned MB heads and always liked them. Very simple, yet effective - I've had all EQ controls between 11 o'clock and 1 o'clock at all times.
Plug it in, tweak a tiny bit and you're set.
I think the two strongest factors that can bring people to dislike them is their strong and bold choice concerning color (I dig yellow), and the fact that the sound of their equipment is quite direct. A sloppy player will sound sloppy. A bass that's below par in the sound quality will sound below par.
There's not much to mask that and not much to hide behind. Just plain old what you put in there comes out louder.[/QUOTE)
I love that clarity... whatever little subtle something one does on the bass comes out loud and clear.
I've mainly got a Steinberger L2 going into mine, so that really is Clarity Plus... occasionally a Rickenbacker 4001 or a Wal fretless and all three have a habit of being clear as a bell through a Markbass... I love that.
I know it sounds odd , but I use a Marshall head (the only head i have ATM) and that still has that focus.
