Wampler

Brian Wampler founded Wampler Pedals, Inc. in 2007 as a guitar effects pedal company. Wampler started out by modding existing pedals before making his own designs. Wampler was active in the online DIY pedal-building community and self-published a series of books on guitar pedal design that helped launch the careers of other boutique guitar pedal builders. The very earliest Wampler pedals were made in Brian's garage, before production was moved to a factory in Kentucky and circa 2019 Wampler effects were made and distributed by Boutique Amps Distribution in California.
