This is one example of a common modification on a vintage Astatic JT-30 microphone.
We replaced the old element (MC-151) with a new one, replaced the 3-pin xlr jack with a new tight 1/4" jack.
We also added the TRS touch by attenuating the volume control (20%) to reduce feedback, as well we added our mod kit to smooth the high end frequency response. Very nice!

Dan Echo Mod
This modification was done to the "Dan Echo" guitar echo pedal in order to accommodate a 1/4" jacked harmonica microphone to be plugged directly into the input without any signal loss, mismatch or distortion.
