90-95 Rhoads Pro ? including the active tone control, (9v battery in control cavity).

So im reading up on some things. I had no idea these had a 9 volt for the tone control. I guess I can take the cover off. Am I going to see a hugh difference in putting a new battery in?

Guys
Oh 1 more thing is it the same for a 90 soloist pro? Or any 90-95 pro?

Sure as shit my Rhoads Pro has the 9 volt and my Rhoads Standard Pro does not..
Changed it out still has 2022 as experation date so it must be working this whole time. Still changed it out just because.
