Fully Tested and Working

Here’s rebuilt Vintage Astatic Model JT30 harp mic, with an excellent, strong, vintage Shure controlled magnetic element from 1977. I’ve fully rewired the mic. The connector is a Switchcraft 5/8” screw-on model. The paint is Grey with Chrome grill. Good condition considering the mic is 50 years old or so. Pay attention to the photographs for some flaws on the grill.

This element is strong, with a nice distortion throughout, and excellent bass tone. The new transducer gasket is from Jeffrey Spoor, and seals the shell casing for the best response from the element.

Cosmetic condition includes some scuffs and scratches to the original grey shell and grill coat.

The microphone has been fully tested on a Lafayette PA-10 amp head driving a twin-ten cabinet with Lil’ Buddy speakers. Sounds excellent. Ready for the stage.
