Removing Rockola 1422 Selector Buttons

I am wondering if there is a "trick" to remove the selector buttons from the Rockola 1422. Or is it just persuading them to come off?

If attached to the shaft--pry evenly, and carefully--expect to need to glue them back on, if you are not replacing them--

Ron,

I figured it out while you where leaving the message.
The 3 buttons that I was working on were really stuck, the others came off fairly easily.

Enjoy the holidays with the family!
