SM57 Impedance Gizmo

[AudioGeekZine]

ok so I just a 500ish Ohm resistor to the one I opened.
Did a quick recording comparing stock to modded. Same position, as close as possible for a lazy fuck like me.
Sounds like a different mic position. Different, better? not sure. Takes a bit more gain than stock, nearly the max the preamp has with the amp at low apartment levels.

I also discovered you can't just plug a guitar cable from the output of a PF2626 to my amp (worked fine with the 002r) Noisy but not the sort of noise I'd think you could avoid by using balanced cables or reamp box. It's a bit like plugging a laptop into a PA system, digital roaches crawling around or something.

does removing the transformer increase the impedance or decrease it?

 

[everybody's x]

slightly off topic, but seeing as sm58s have exactly the same capsule as sm57s, if i take the pop shield off my 58 i actually have a 57? or is some of the electronics different?

Yes it has the same capsule and the same transformer

Couldn't one just add a switch so you could switch the transformer on/off???

Yes, but since drilling through the body wouldn't be much fun I'd take it out and put the transformer and switch on a separate cable.
