After discussing my idea further with Pat today, he suggested that I add an actual paper calendar to the amp to make the usability better for the user. After giving this some thought, I think it would be a great idea as you could replace the paper calendar every year yet the actual outer amp would last forever, so even if you didn't replace the paper bit, you could still use the calendar.
My initial thought was to put facts on each month about Marshall but after doing some research, all the important info didn't state the month but only the year. So I've decided on each month I'm going to put a famous guitarist who was born in that month with their birthday in the corner. These guitarists will also be people that use Marshall amps or who have done in the past.
