well, sry, i didnt really understand what exactly your problem is, but you may have to set the equalizer.

you said you have Level, Gain, Low, Mid and a Hi knob?


well, i for metal you could use very much low, very less mid and about 3/4 high.
i guess gain and level are for your own prefernce.

I am using a Metal Core -like setting at the moment, very much low and high and very less mid, of course with nearly full distortion. (Bandit rules distortions! ^^)


i don't know your pedal (the only pedal i know is Boss ME50 or sth like this, and i dont know much about it xD), but maybe the level knob is for the type of distortion, so for example i have 3 types: hi-gain, modern and vintage. normally i am using modern.

i hope i could help somehow... ^^"
