The drummer was upset to learn Foote's store was under threat of closure, so he teamed up with the business' long-time sales director, Rob Wilson, to buy the shop.
He tells Britain's ITV News, "I was very disappointed when I heard that Foote's was going to close because it is one of my great memories of being a young, budding drummer, going to the original shop in Denman Street and buying my very first kit for £7.50.
"The thing about a drum shop... it's the place where information gets passed around. You hear about new things... if you need a drum lesson, the best place to go is probably a drum shop and ask them for advice."
Despite his investment, Mason insists he won't have a significant involvement in the running of the store, adding, "I think I will try not to be too hands on. I doubt that I'd be very much help really. I'd love to come in occasionally and keep an eye on things and see what's going on but I don't think I'm going to be behind the counter on a regular basis."
