On every patch my last 3 pedals are a volume pedal, delay, and reverb. I set the volume pedal to a minimum setting of 70% and a maximum of 100%, so all I need to do to get a gain increase is step on the pedal. It's much easier and a lot smoother transition from rhythm to lead than programming a button to increase the volume using an EQ. Plus doing it this way it allows me to get my sound and then simply make it louder without changing it. I've seen videos of people saying to assign the pedal to the output of the amp. Not only is that very inconsistent, because all amps are designed different, it also changes the tone. Many amps get more distorted with their volumes all the way up. My way is just like having the sound guy turn you up and down. I'm in a 5 piece, so you may want to experiment with the minimum settings.
