10k or 100k stepped pot---how do I test?

I have a BEZ Q3b linestage and wanted to replace the pot. However I don't have the manual and wanted to know how do I check to see if it's a 10k or 100k for a replacement. I do have a multimeter. Thanks in advance.
Every one I have replaced has value printed on case. Sometimes you need a magnifying glass.
Thanks Magnumpi205,

I opened the BEZ today but didn't find any values. I guess I'll need those magnifying glasses. Perhaps someone familiar with the BEZ line could steer me in the right direction.
