For a long time I have noticed that when I play different brands of instruments on say alto sax or clarinet that I get different ideas when I improvise. I have heard people talk about the same thing in terms of changing your environment to allow for different ideas. I suppose the idea is that we get set in our ways in certain spaces which is why I hear a number of people say that they get great ideas on walks or hikes. I believe the same thing is true with your playing. If you want to experience some different ideas from your fingers try a different horn.
