The Fundamental Tremolo is a classic optical tremolo, giving you that iconic chewy movement, with the tonal integrity to live on a professional's pedalboard but with simplified controls friendly enough for even the newest effect pedal users. With 3 wave shapes to select from, you can get sounds from smooth and soothing to glitchy, wild, and crazy.

Each Fundamental pedal has three faders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of pedals that will keep you covered from your first band practice all the way to a sold-out arena. Designed and assembled at Walrus Audio headquarters in OKC, OK.
