This Blues Blaster, Hohner’s version of the vintage JT-30 mic, has a great, strong, 1973 Shure Controlled Magnetic element inside. This is a wonderful improvement to the stock crystal that usually comes with the BB. Nice gritty tone. Breaks up nicely on the lows when cupped, bright and crisp when open.

This microphone has been fully rewired, and a new, properly configured, Alpha potentiometer has been installed. The volume control is smooth, and easy to grab with the knurled knob.

Excellent cosmetic condition, but there are a few nicks and scratches in the blue finish. Please look carefully at the photographs.

The mic has been tested on a Mission Chicago 30 watt amp, and on a lovely little Kalamazoo Model Two amp. It performs great on both.
