1940’s Astatic JT30 B-Series, 1974 Shure CM Element


Blemished Original 1940s Gray Finish JT30
Chrome Grill with corrosion

Excellent Crunchy Tone!
High-Impedance Harmonica Microphone
Vintage 1974 Shure Controlled Magnetic
99A86 NB element
Fully Tested and Working

A rough Astatic JT-30 in fair cosmetic condition, with a small scratches, discoloration of the shell and grill. It’s newly rewired, with a Switchcraft cable connector, new element gasket, premium volume control, and an excellent Controlled-magnetic element from 1974. I’ve also added a dual windscreen behind the grill featuring marine-grade stainless steel mesh and black nylon cloth.

Tone-wise, this mic is crisp with good lows and great distortion. Better than any of the new harp mics available today.
This CM element sound is what’s important, and it howls!

The mic features:
– Strong 1974 Shure 99A86 NB element
– Original Glossy Grey Marbled Paint with flaws
– Switchcraft 5/8” screw-on connector
– 1019 Ohms, Strong element
– Integrated Volume Control
– Custom stainless steel mesh

Rough cosmetic condition and corrosion and scuffs on the grill.
