The proud owner of a JTV 89, I recently acquired a Variax 500 as well and have decided to paint the guitar. My question is thus: How do I remove the rotary push pull guitar model selector switch? Everything else seems pretty straight forward on this guitar, but I'm not sure how to remove that switch. The knob doesn't seem to lift off like "normal" control knobs do and the knurled top of the control knob seems too solid to just unscrew, thereby allowing me to remove the labeled part of the control knob and subsequently, being able to access the jam nuts for removal of the push/pull rotary pot from the body. Any help is appreciated. I've looked high and low on this topic and can't seem to find any information on how to remove these bad boys. Thanks so much.
