yeah it is a vox wah pedal, the bong is weird looking cuz i happened to break half of its glass off thats why its so short, it was previously alot longer, but what i did with it is i kept dipping the jagged part into wax over and over and formed it into that shape, i think its way sweeter then before. plus the wax is blueberry scented so when i smoke it kinda tastes like blueberries. that is some quality stoner ingenuity
