[Harp-L] Butterfield's mic

[Greg Heumann <greg@xxxxxxxxxxx>]

I agree with what's said in the post below and would only add that  
some of the early PE54's were shipped with a single impedance, high  
impedance transformer. That to me had the best sound of any of the  
combinations.

545S, PE54 or both?  Which one was the real Butter's Pistol??


  It was said that Butter used both, but wired to high impedance.   
The 545S (S stands for "switch" used to turn the volume on and off.   
The 545S that Butter used has a pistol grip and is relatively heavy to  
hold.  The PE 54 is no doubt more comfortable, tho I never held one  
myself.
 On G's site (New Zealand harp expert who used to be a frequent  
contributor to Harp-L), http://www.angelfire.com/music/harmonica/ ,  
under the amplified harmonica link is a page devoted to these two  
mics.  I suggest u go there and read all about it, and bookmark his  
home page -- the webite is filled with interesting and useful info:http://www.angelfire.com/music/harmonica/shure545.html 
 .
 An excerpt says:
The Shure 545 UNIDYNE® III and PE54 UNIDYNE® III serieswere all fitted  
with the same R45 Dynamic Cartridge, as was the Shure544 UNIDYNE® III.  
The internal 51E23 transformer has low impedance andhigh impedance  
windings, and is what makes the mic so powerful andversatile. If these  
transformers were provided with SM57 and SM58, theywould be equally  
treasured by harp players.The only real difference between the 545 and  
PE54 mics was the 545 wassold setup for low impedance, and the PE54  
was sold setup for highimpedance. With the exception of the first  
PE54, and 545L, all thesemics can be switched to high or low  
impedance. The 545L is the onlymodel that cannot be wired to high  
impedance.
