When a famous drummer endorses a brand of drums, what is the typical deal they get? Is it one free drum set?, or all the drums they want?, or just a discount off the price?, or is it totally different depending on how famous they are? Is it different with every brand? What is the typical deal a famous drummer gets for endorsing & playing a drum brand (like Gretsch, Ludwig, Sonor, DW, Tama, Pearl, etc.)??? Thanks. - Not sure of where to post this question.
