"This is the Creation Audio Labs boost pedal, and I use that just for a slight lift, if I'm just using the Marshall, which I don't set on clean, I set on some crunch sound, this will take me to in between a rhythm sound and a lead sound, like a quieter lead sound, so it just gives me a step up there." - Frampton about Creation Audio Labs MK 4.23 boost.
