ZVEX Effects is an effects pedal company based in Minneapolis, Minnesota. Their name derives from the name of founder Zachary Vex who is a respected innovator in the business, and by some described as a “mad scientist”.

The company’s most famous product is the Fuzz Factory. All of their pedals (except the budget-line Vextron series) are hand painted at their factory in Minnesota. All Vextron subassemblies are made in Taiwan, but the final assembly is completed in the United States.
