The Armbruster black aluminum knob keeps the styling simple with a white painted indicator and vertical textured grip. It's a super-versatile, professional look.

What's in a name? We call this knob "The Armbruster" after customer Olivier Armbruster who came to us looking for a knob at these specs. We listened to him, sourced it, and are proud to now offer it in the store.*

*Do you have a product you want us to carry? Contact us! Just don't think that if we source something for you we are automatically going to name it after you. (The guy's name sounds like a character from an '80s Arnold Schwarzenegger movie for Pete's sake. If your name is super-boring like "Dave Smith," it ain't gonna happen.)

**Unless of course you are The Dave Smith, Synth Pioneer of Greatness. In which case, we will absolutely name it after you.
