Description

Edit description

The Keeley ECCOS is a true stereo delay and looper pedal that brings together the vintage charm of tape-flanged echoes and the versatility of a modern looper. The ECCOS, a product of over three years of development on the Quad 24/56-bit Dream DSP, offers unprecedented control over tape-style echoes. You can create long, majestic-sounding tape flanged delay lines and then switch to the feature-packed looper to record endless layers of sound.

The dual stomp switches serve various functions. In delay mode, they can be used for true-bypass, tap-tempo, and endless feedback. In looper mode, they allow you to record, play, reverse, half-speed, and even trigger a "play-once." Both the delay and looper can work independently, giving you endless room for creating and experimenting, whether live or in the studio.

The ECCOS also features a 'Sound on Sound' mode that lets you record without erasing the original loop, recreating a vintage reel-to-reel recording technique. This balanced and versatile pedal is sure to become a staple in your gear setup.

The Keeley ECCOS offers an enticing blend of analog delay and flanging effects, allowing users to replicate classic sounds with impressive precision. Its capabilities for seamless switching between delay and looping modes enhance its versatility, making it a dream for creative players. However, navigating its multi-function menu can be cumbersome, and accidental adjustments to settings may frustrate some users. Despite this learning curve, the ECCOS' rich tonal palette and robust build make it a worthy addition for any pedalboard. Overall, it's a compelling choice for musicians seeking depth in their sound design, albeit with a need for patience in mastering its features.

5 Star Delay. A weirdo in sheep's clothing.

First off, it's a very good delay. Sounds good and has the ability to change the tone of the repeats, meaning it can be a dark delay or a sharper, edgier delay. The looper is great and I love that the delay can still be used/changed when using the looper

But it really shines with its secondary features. The repeats can have a flange OR a vibrato, each being tweakable from subtle modulation to total seasickness.

And for those who like to get weird with their music, the Sound on Sound mode in the Looper section. Endless fun and really good for experimenting in layering and Frippertronics type music.
