Juno stage Master-VR and Mic-VR pots

Hi guys!

I need to replace these two pots on my Juno Stage. The Volume-VR pot is a stereo pot and, according to Syntaur shop page it’s a 50k x 2 pot (is it logaritmic or linear?), while I can’t find information about MIC-VR pot value.

Can you please help me to discover this value?

Thanks in advance for the reply!
