Walrus Audio Fundamental Series Lo-Fi Delay

The Fundamental Lo-Fi Delay turns familiar echoes into shifting, imperfect textures. Designed and assembled at Walrus Audio headquarters in OKC, OK, this pedal was created to provide the tonal integrity required to live on a professional's pedalboard, while featuring simplified controls friendly enough for even the newest effect pedal users. Whether you want subtle movement, hazy ambience, or shifting rhythmic patterns, three sliders and a three-way switch make it easy to find your sound.

With three distinct delay algorithms, you can move from bright, wow-and-flutter-soaked chimes to dark, undulating clouds, or build rhythmic, multi-tap echoes with analog-style character. This pedal will keep you covered from your first band practice all the way to a sold-out arena.

Key Features

  • Three Delay Algorithms: Use the slide switch to select between AM (bright with gentle pitch movement and a fading radio signal texture), Murk (dark, dense, heavy distortion with low-frequency modulation), or ECHO (rhythmic, multi-tap delay with analog-style tone shaping).
  • Simplified Sliders: Three faders give you instant control over Time (up to one second), Feedback (from a single echo to infinite repeats), and Mix (fully clean to 100% wet delay).
  • Tap Mode & Divisions: Hold the bypass switch to engage Tap Mode. When engaged, the secondary slide switch controls your tap divisions, allowing you to select between Quarter Note, Dotted Eighth Note, or Eighth Note.
  • Trails Mode: Active by default, allowing your delay repeats to fade naturally after the pedal is bypassed. You can easily deactivate this for an immediate cutoff by holding the bypass switch while applying power.
