Funny, my machines aren't the least bit dodgy nor do they have any trouble staying in tune. The only thing I don't like about them is the indentation on the barrels: stupid design.
I didn't mean to imply that my original CV machines detune by themselves. I sometimes have a tendency to *lightly* bump a key with my hand/fingers when I am dialing in, hence the inadvertent detune. I call it "fat fingering", like striking two or more adjacent keys on a keyboard or keypad whilst texting. When I got the bass, I made sure that all screws were tight. If there is an issue down the road, I will upgrade. I don't mod for its own sake, other than what I've done already for aesthetics or personalization.
