All Cosmo type bakelite knobs on the Voyager (and Minimoog D) are held on the shaft by a setscrew on the side. Which can be unscrewed with either a 5/64" Hex Key (or Allen Key), or a small flat head screwdriver depending on the setscrew type used.
No need to open anything.
I have MF pedals with Cosmo knobs that are secured by friction on a D-shaft - no setscrews.
If you’re serious, I’d be keen on yours (if you don’t have anyone else in mind of course!) and pay for shipping etc.
Maybe it will fit on one of my Phatties, Moogerfoogers or the Minitaur..
Cool idea anyway - Moog, I’m impressed!

Yeah MC, that’s why I specified knobs on the Voyager and Minimoog D. 
Faithful Voyager OS owner. Sad because it’s second hand. No knob for this guy 
You’re welcome to it - unless they suddenly start changing hands for huge sums on ebay, which I doubt.
I’ll let you know if Moog send me one, though I haven’t received the email from them yet. Someone was saying recently that Moog don’t seem interested in anyone outside America. As I have a British issue Voyager that doesn’t have the Moog logo and Moog don’t seem the slightest bit interested in providing even a sticker to badge their instrument, this comment rings true.
People, people, let’s not forget that Moog Music will have to sort through tons of sent confirmations to validate each and everyone of them with their records, before starting to ship said brass knob…
That may take a while…
Awesome - I appreciate this, it’s very nice of you! 
I won’t hold my breath obviously, but rather treat it as a bonus if I do get one.
BTW That’s interesting about the British Issue Voyager. I didn’t know there were logo-less Voyagers around..
Cheers,

Yes, of course that will take a while.
They’ve had since 2005 to send the Moog logo sticker, and still no sign of it. 
So what about us RME owners? No setscrews on our knobs and the cutoff filter knob is slightly smaller than on the full sized Voyager. How do these work on an RME? Amos?
Usually, knobs with a setscrew can be installed on spline shafts, or D shaped ones. Although they might turn slightly askew, or off-center.
Just checked my XL. No set screws.
Have an early PE here, and all the large knobs have setscrews. So there are 5 large knobs, LFO rate, osc 2 & 3 frequency, filter cutoff, master volume. All the rest are on D shafts and a friction fit. All the knobs on the RME here are non-setscrew type.
Brass filter cutoff?
Nice try, photoshop guy…
But the angle is a little off…
Woow…thanks Moog!
It will look awesome on my Voyager
You can register it anyway. If something goes wrong, contact moog people (Perry in this case).
I have a second OS too and was mailed.
Thanks be to Moog…loving the knob, clever idea!
How do I get a full set?
You could always take your existing knobs and dip them in gold color paint ?
Ah, so you are getting the purdy knob? The original owner registered it and purchased the extended warranty. I was told that the standard warranty doesn’t transfer, but the extended does. Last I heard was that the original owner gave Moog the OK to transfer to me and I sent an email requesting this be completed, but it never was. I just got a call in to Perry now. Hope it doesn’t slip by again.
want that knob!
