201 Pocket Piano knob size

Was real happy to get a blue 201 Pocket Piano yesterday and I always like customizing my synths in little ways. What is the size of the knobs on the 201? I’d like to replace them with some different colours.

Thanks for getting a 201!
The pot shaft diameter = 6mm. ‘D-shape’/flat of shaft is 4.5mm
Pointer should be 180-degrees from flat.


thanks for the info!

What’s the safest way to remove knobs? Do they just pull off? Thanks!

Yes, just pull straight up.

Got the knobs I ordered today. Dark grey and dark blue cause I couldn’t decide.


“DAVIES 1900H CLONE – D SHAFT” from Thonk if you’re looking to do the same.
