I'm looking for a bit of help with narrowing down my choices on a distortion pedal. 
 
Ideally I would like: 
mains powered 
valve distortion/overdrive 
direct/effect blend or levels 
No bass loss 
 
The sort of sound I want is from a Song2 type distortion to a slightly dirty overdriven valve sound. 
 
Any suggestions to save me trawling the shops endlessly much appreciated.
