Description

Meet your new pedalboard companion, the Walrus Audio Fundamental Series Delay Pedal, designed to deliver exceptional delay effects with effortless operation. This pedal is a marvel of streamlined design, offering three intuitive controls - Time, Feedback, and Mix - to help you craft your ideal delay effect.

Time gives you the reigns to determine the lag between each delayed note, from simple slap-backs to sprawling echo chambers. The Feedback control allows you to inject your sound with just the right amount of ambient chaos, while the Mix control lets you decide how subtly or prominently you want your delay effect to be.

One of the most striking features of this pedal is the 3-way mode selector. This nifty tool allows you to toggle between Digital (for a clear, copied delay), Analog (for a warm, gradual signal degrade), and Reverse modes, giving you a wide palette of sound design options. For added convenience, you can establish a tap tempo simply by holding down the footswitch, making it easier to sync your effects with the rhythm of your music.

Key Features:

  • Designed for both pros and beginners with intuitive controls
  • Time, Feedback, and Mix sliders for precise sound shaping
  • 3-way mode selector for versatile sound design options (Digital, Analog, Reverse)
  • Tap-tempo enabled by holding down the footswitch
  • Ideal for creating a range of delay effects, from simple slap-backs to ambient soundscapes

Critic Reviews

Walrus Audio Fundamental Series Pedals review | Guitar World

guitarworld.com

Walrus Audio's Fundamental Series Delay delivers a sleek design packed with sonic versatility, boasting three distinct delay modes that cater to various musical styles. The compact footprint and solid sound quality make it an excellent choice for both beginners and seasoned players. However, the placement of the power socket is a notable inconvenience, as it disrupts the otherwise tidy arrangement on pedalboards. Overall, this pedal shines in functionality and aesthetic, making it a worthwhile addition to any rig.

Walrus Fundamental Series pedals review | MusicRadar

musicradar.com

The Walrus Audio Fundamental Series Delay stands out with its impressive modulation capabilities and thoughtful design, making it a solid choice for both newcomers and seasoned players. However, the top-mounted jacks and side power input can be inconvenient, and while the delay modes are versatile, they lack the depth of some pricier options. Overall, it’s a functional and attractive pedal that delivers great sound for the price, though it might not dethrone higher-end competitors.

Walrus Audio’s Fundamental Series is redefining entry-level pedals

guitar.com

Walrus Audio's Fundamental Series Delay impresses with its impressive range of authentic tones at an entry-level price. With modes for digital, analog, and reverse, it offers versatility that belies its $129 tag. The tap tempo feature is a standout at this price point, adding to its appeal. However, the side-mounted power socket detracts from an otherwise well-designed layout, and the accompanying Phaser, while decent, feels a bit underwhelming compared to its counterparts. Overall, these pedals are not just for beginners; they deliver quality that could satisfy even seasoned players.

It’s stupid good for the price!

This thing has everything and I mean everything you could need in a delay. My only bummer is that while it does have tap tempo, you have to hold down the switch to tutn it on which you means you can’t bypass the pedal unless you hold down the switch again to exit tap tempo before hitting the switch again to bypass it. It would be perfect if it was a separate switch but at this price, I’m surprised it even has tap temp.
