This is a great post from the ReverbNation blog that sets out the nreleatively simple idea of making a tier of products available for different types of fans.
The following illustration is an attempt to visualize four types of fans that buy for different reasons. Any given Artist may have fans in any or all of the buckets, depending on where they are at in their career. You’ll notice that I added a ‘value’ arrow that increases as you go up the illustration. This value arrow is based on a combination of the price each type of fan is willing to pay multiplied by the number of potential fans in each group. Your biggest supporters are willing to pay more than some of the other groups, but there will likely be fewer of them, especially as you tour farther from home.
