Mark - the Fireball has reasonably high output AND pretty good  
feedback  rejection, but there are a couple of very important  
variables. First, mics simply differ in output  - even among those  
with the same element in them. The output of crystal mics, for  
example, drops with age until they are no longer playable. So... you  
should dial your amp to each mic independently. It doesn't matter so  
much what number the volumeknob is  pointing to when you're done -  
only that you're happy with the sound and level. Second, the Fireball  
is a low impedance mic. Therefore you should be using an impedance  
matching transformer to plug into your Blues Jr. Different impedance  
matching transformers will have (get this!) different impedances - so  
some will have higher output than others.
