Engl e530 Cam vs. Sm57 vs. Impulse High Gain Comparison

Sounds awesome!
Have you ever played the blackmore?
If yes, how would you compare it to the e530?
Some people say they're pretty similar...
 
I dig the miced version. It has an awesome "angry" voicing. I should consider it as another amp for practice..Too bad, that the internal poweramp seems to have only a 4ohm output.
