There's a very simple answer, money. "Influencers", and I really hate that term, are nothing more than paid advertisements whether it be from ad revenue, direct payments/free gear, or business connections. A video on Vertex's youtube channel features Rhett playing one of their pedals. He was most likely paid for that performance, though I can't say for sure, and that's fine. He's a talented guitar player and musicians have to perform to get paid. However, he's not a household name or a platinum recording artist. If he was to start turning down those offers, it would have a direct impact to his bottom line.What seems different to me about this masonic character is that the Rhetts and the RJs of his world all (and I mean ALL) preface their shillings by saying “My friend, Mason Mangella...”). That’s just bizarre! Are they really all friends that bonded over some insecurities? Are they paid to stick that exact phrase in their vids? Is there some bizarre NXIUM-like sex-cult brainwashing going on? Whatever’s going on, it’s very cringe-y. Caveat emptor!
Let's say Mason paid me to make a video about one of his pedals so he could use it as part of Vertex's marketing. He still has other pedals and products out there that he wants to advertise. If I say nice things about him and his products in my personal videos, it's that much more likely I'll get his repeat business. I'll also be seen as a friendly and reliable outlet to other manufacturers. I may not get a big engagement from the likes of BOSS but with enough contacts at smaller companies it all starts to add up.
