If you use a Shure 545 or SM57, you’re not alone. These are wonderful harmonica mics and are in wide use. However their small diameter can make holding and cupping them uncomfortable. Over the last few years I’ve had many customers ask “Can you fit an SM57 or 545 element into one of your wood shells?”
The answer is no – the cartridge of these mics is about as long as a typical bullet shell’s outside dimension, and then there’s a transformer (located in the barrel of the standard mic) and the connector that have to be accommodated.
The Bulletizer is the solution. It gives you a larger surface to grasp and cup, and provides an acoustic chamber inside your cup to bring out the best of the mic’s tone. You can even “tune the tone” by varying the position of the mic inside the shell.
The Bulletizer’s outside diameter is 2 inches, making it very easy to cup, even if you have small hands. By comparison, a JT30 is 2.35 inches in diameter.
The Bulletizer is easy to install and remove, and fits very securely on your mic. To achieve this I machine each one in my own shop, to very close tolerances for an exact fit. For this reason it does not fit other microphones. It fits Shure SM57, Beta 57 (not Beta57A), 545 and PE54, and BlowsMeAway Ultimate versions of these mics.
