I may never know. They say you crank the volume of the channel and turn the master down, but I actually prefer the sound of cranking up the master and turning down the volume. I conclude both need to be cranked to find out how heavy this thing really gets.

All i know right now is there is not enough gain for me. I like the way the drive sounds, theres just not enough of it. Any suggestions on some good booster pedals?
