The Walrus Audio Fundamental Delay delivers essential delay tones with a streamlined interface, making it ideal for both beginners and pros who need reliable, musical echoes without fuss. Featuring three distinct delay algorithms—Digital, Analog, and Reverse—the Fundamental Delay covers everything from crisp rhythmic repeats to warm, vintage-style echoes and dreamy reverse textures. With up to one second of delay time and full control over Time, Feedback, and Mix, this pedal adapts easily to any playing style or genre.

A three-way slide switch selects between delay modes, while a secondary function in Tap Mode lets you choose tap tempo subdivisions: quarter, dotted eighth, or eighth notes. Enter Tap Mode by holding the footswitch until the LED blinks, then tap in your tempo on the same switch. Trails Mode is also included by default, allowing your delay repeats to naturally fade after bypassing the effect, with an option to disable it for an abrupt cutoff. Designed and built in Oklahoma, the Fundamental Delay brings classic delay functionality into a compact, user-friendly format.
