RE: [Harp-L] Volume control for shure 520d

[Tim Dougherty <timd@xxxxxxx>]

Kieth's description for the "Rod Mod" on the JT-30 site are specifically 
meant for a crystal element.  According to Dave Kott, the magnetic elements 
used in bullets should be around 500k.  I'm convinced that he knows more 
about bullets than anybody else on the planet.  Having said all that, I put 
5 meg pots in several of my mics with magnetic elements before I knew 
better.  The only real negative I've found is that all the volume 
adjustment occurs between 8 and 10, so minute turns of the knob result in 
big volume changes.

You can reach Dave at grbullets2@xxxxxxx
