Hi, i play heavy metal and I want to get an eq pedal, i recently discovered that its best to put it in the fx lopps than on the front of the amp, i just saw this on a youtube video and it kind of makes sense to me. i can see that the pedal will start to eq the signal depending on the place you put it. But my amp lacks of this feature, i have a Marshall CFX30. So whats best? New amp with fx loops? or in front of the amp? thanks!!
