These guitar effects pedal cushions are made by Gwendolin Tägertof of Soft-Machines. You can buy the Electro-Harmonix Big Muff Pi for 120 Euros or the RAT distortion for 99 Euros.

When Electro-Harmonix found out about these, instead of threatening to sue Ms Tägertof, they offered her a formal license in exchange for an option to buy them at a discount.
