The output problem you are having is an impedance issue.  Your SM57 
is low impedance, for which the Snap-On is designed.  The JT-30, 
despite the XLR connector, is high impedance, and won't drive the 
Snap-On properly.  On my JT-30, I use an XLR-to-1/4F adaptor, and 
plug an AKG "guitar bug" (designed for high impedance) transmitter 
into that.  I got the two transmitters (Snap-On and Guitar Bug) in 
the same frequency so I can use the same receiver for both.  

The colors for the battery covers designate the frequency on which 
the transmitter broadcasts.  AKG publishes a table that shows the 
frequencies and their designated colors.  

Hope this helps,
