[Harp-L] Mic Impedance Transformer

[Greg Heumann <greg@xxxxxxxxxxx>]

Joel,  the Fireball uses what is basically a vocal mic element. An  
impedance matching transformer will make the mic louder and a little  
fatter - but it is simply not the same kind of mic as a JT30 or  
vintage Shure Bullet (controlled magnetic or controlled reluctance).  
Those mics distort when you drive them hard - the Fireball doesn't. If  
you like a clean sound or want to use guitar pedals to manufacture  
your distortion for you, the Fireball is a great mic. If you want to  
drive your tube amp to warm fat distortion the old fashioned way, I  
strongly recommend a traditional bullet or Shure 545.
