@david7 I’ve never played the ultimate 57, but I’m sure you’d be happy with it, if you’re looking for a clean sound, or perhaps another option I just heard about would be the Suzuki HMH-200. Suzuki HMH-100 Harmonica Condenser Microphone - #4 by Luke
But if you’re just looking at ergonomics, but still want the bullet sound, then I’d HIGHLY recommend the LoneWolf Jason Ricci mic. That’s what I use for blues gigs.
