Front panel knobs - single + dual concentric that match?

[tristanc]

This is about the build detailed here: https://el34world.com/Forum/index.php?topic=32040.0

Attached is how it looks today. I'd like to finish it off - getting a front panel made and, if I can find suitable knobs, move a concentric pot from the rear to the front.

Can anyone recommend a knob style that has matching single and dual formats? Ideally available / in stock somewhere.

I know I can get chrome / alu dual concentric knobs, and also single versions - this will be my fallback. But are there any more options people could suggest that would complement the build?

For those interested, I have 2 gain controls and 2 mid controls. A gain control after the 1st and 2nd stages, and a mid control between 1st and 2nd, as well as one in the post-CF tonestack. 2 gain controls is like the AX84 High Octane. And having another, early, mid control allows me to do a bit of a scoop early on in the signal chain a la Fender, but also have post clipping control too. I've yet to experiment with the centre frequency of the early mid control - it's set to 600Hz currently.
