I have lots of guitars, all expensive and some quite collectible.
All I do is play the guitar whose sound I want to hear on that day.
Sometimes I have two, three or four of them around me and play the same piece on all.
I see it as fun thing and don't take it too seriously.
Remember that guitars sometimes sit in their cases for a year or two or even more before they're sold, with hardly any playing.
I think a lot of people are under the impression that if they're not constantly playing their guitars they're somehow going to go backwards and close up within a week or a month of no playing. It's not like that AT ALL!
