Transistor question...

Transistor question...
OK...I'm a dumbass...  
 
The pin with the arrow is always the emitter, right?  
Under this ASSumption, I ran into a snag with my  
Tycho Octavia circuit. It seems Q1 (in my case,  
an MPS-A18) works when I put it in backwards. If  
I put it in as the schematic says, it lets out a  
high pitched squeal.  
 
I tried the exact same thing with a 2N5088 and it  
works when it is done the reverse of the schematic.  
I haven't used either of these transistors before.  
Were the both reversed biased out of the box?  
Strange...
