About WALRUS AUDIO

Walrus Audio is an effects pedal brand founded in Oklahoma, USA in 2011.
It is characterized by its cutting-edge and sophisticated sound and art design, as well as its innovative, original and high quality.

(From the official website)
Walrus Audio was born in 2011 from a small guitar circle in Norman, Oklahoma, USA. Since the launch of the Voyager overdrive, the product lineup has grown to 25 models. Walrus Audio is a group of artists, musicians, engineers, video game nerds, road bike lovers, and cat lovers. We get together every day to think about how to make this "little box" that creates big hits. We value the perfect balance between art and sound in our product concepts.
"What's the best local coffee shop?"
