The Walrus Audio Fundamental Series Distortion is a 3-mode distortion effects pedal covering a wide range of sounds from dark and doom through sharp, cutting leads. The Fundamental Series was designed to offer the tonal integrity that’s required to live on a professional’s pedalboard, but with simplified controls friendly enough for even the newest pedal users. Each Fundamental pedal has three sliders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of eight pedals that will keep you covered from your first band practice all the way to a sold-out arena.
