Hie...here i am again..with some silly question...

My amp...have the 3 control knobs..
The low, mid, and high..(or..its the bass, mid, and treble control knobs..)

But i dunno how to set them..to get the right sound..

can you all teach me how to set them?

I mean...if i want the rock or metal..sound..what should i set them??

If i want some light and ryhtymic acoustic sound..how should i set them??
and also other fiffs sounds..

also how you all set them ?? by default??

thanks..
