The Hohner Blues Blasters are still being made with small crystal elements made in Japan. I've played a few of them, two of them that a guy who bought 2 Blues Blasters sent to me to swap the crystals for vintage CM's. He didn't even want the crystals back! Since then I’ve had a bunch of new Blues Blasters sent to me to swap elements in because the new crystals are very high gain, thin and squeaky sounding with no nads at all! So I guess there’s no need for me to comment any further on those!

The Newest Green Bullet
Now the 520DX mic is a different story. That’s because it's a different animal. The new 520DX has a regular dynamic element with a plastic diaphram in it. Shure claims it was made to sound like the old ones, but it's not quite cutting it with many harp players. It does have a decent tone, and many players like it, but it's much less raspy than the vintage mics and just doesn't sound like a vintage green bullet. It does have it's place in that it really doesn't sound like any other harp mic on the market, and some players like having a mic that is somewhere between a 520 and a vintage vocal mic.
