IMA is a hype-man. I appreciate that he's found some professional success as a player, and a lot more as an internet personality, but I haven't seen enough originality as an artist/bassist to take him seriously enough to buy whatever he's selling. He's a good player, he's seemingly more successful than I have ever been, but he's basically just an "influencer" rather than (IMO) a bonafide bass artist.
He seems like a cool guy, so I won't dog him on that, I just get the idea that all the signature gear and strings and what not are more due to his internet persona than his prominance as a professional bassist (in the vein of Sean Hurley, Pino, Lee Sklar, or Tim Lefebvre, etc.).
But maybe I'm wrong.
