As you all know, the inner mounting "bracket" for the volume knob on your Business CD53 is prone to breaking, making the knob become wobbly and annoying. All it takes is pushing the knob too hard once for the on/off function and boom, busted knob. Well I recently found a great fix and DIY to go with. I ordered this part, used the DIY and it worked flawlessly, took me about 45 mins. It's definitely worth the $30 imho. Cheers
