George used to do a funny bit on 'stuff,' and it made me think of musicians and their 'stuff.'
I know a number of musicians that own multiple instruments. Some of them are eager to have others play their instruments, but others refuse to let anyone touch their prized possessions.
May I suggest that you freely let others use your gear? It's just 'stuff.' You can't take it with you. In a few hundred years it will probably be dust, just like you.
I'd rather have a few 'dings' on my instruments and share the joy of playing them, than to have a collection of 'pristine' instruments that only I played.
Give it try. The next time somebody asks to borrow a guitar or sit-in on the drums, be the first one to offer yours up. It's a 'freeing' experience.
And, BTW, George Carlin was a genius.
