F4me, thanks for the reply.
Actually, yeah, I did do that eventually to take the knobs off. However, one knob was being a pain, and I had to pry it with a screwdriver for it to come off completely, which is why it left a dent on the finish itself.
So a complete refinish is my only hope? That's quite costly, and will doubt that I'll even get to it. Although my friend does have a car painting shop, so I wonder if I can have them do it.
I'll try to do some research into painting, and since I only want the top painted, maybe, I can just tape the neck and other removable objects and have them paint on top of the existing finish. Would that be possible?
My worry is that the car paint might eat into the wood? Or that car painting stripping methods might even destroy the wood.
Hope somebody who has experience with dent fixing can reply so I don't have to go through extreme solutions. Buffing? Steaming perhaps?
