Adriaan,
First let me say, the Monty Bass is an awesome bass. I love everything about this bass. Black Basses are formal as heck, and there's this high-tech Bat-Man like mystique to this bass that I love. The Monty is one of my favorite Alembic customs, and the looks are very striking and it screams PLAY ME!
I am glad you brought the Monty in this custom concept forum for more reasons than the ones I raised, because it is fitting, and I must admit, I was thinking about a black custom, but the Monty was already built, and with the bat-like wings to boot at the tail, fabulous.
As for the control knobs, I would had done the same for the Toma_Hawk bass, but s/he's more primitive than the Monty. The knobs position on the Monty, says High-Tech, and straight lines. It's perfectly done.
On the Toma_Hawk, the knobs are arranged in that old-school way I wish to preserve. My mind is programmed with 4 controls, if I couldn't have 2 stacked pots. When you think about it, 2 is more primitive than 4.
So, if I can't have the two, then give me the classic 4 knobs, arranged in the classic parallelogram shape.
