So I was changing my volume pod on my guitar (Yamaha RGX 121 ZL) and I've so far gotten as far as taking off the volume knob knob thingy. I wanted to make sure that I knew what I was doing, so I attempted to put it back on. It just kinda slipped on, it doesn't have the same feel to it when I turn it.
How can I fix this? Do I also need a new cap now?
