The ECCOS Delay Looper is based on a new stereo, flanged delay tone. Create beautiful sounding tape style delay lines and then spin them endless with the Looper! Designed to be at home in live pro rigs or bedroom studios while experimenting. The Keeley ECCOS is a delay-looper workstation with superb sound quality and abundant features.

The true-stereo Keeley ECCOS artfully combines a delay pedal and a looper. At the heart of the ECCOS is a neo-vintage delay with unprecedented control over tape-style echoes. Create long and majestic sounding tape flanged delay lines and then switch to the feature-packed Looper to record endless layers of sound!

Dual stomp switches in delay mode are for true-bypass, tap-tempo and even endless feedback – but in looper mode they allow you to record, play, reverse, half-speed and even trigger a “play-once”. Live or as a studio workstation the delay and looper work together giving you endless room for creating and experimenting in a small footprint. With over four years of development on the Quad 24/56-bit Dream DSP, Keeley has reached the pinnacle of delay sound quality with the amazing new tones in the ECCOS.

The ECCOS now features Sound on Sound Mode! Sound on sound mode lets you record without erasing the original loop. The volume of the loops degrade over time, recreating a vintage reel to reel recording technique. To set the decay of the loops, hold down the FDBK knob and adjust the Depth control. This alt control comes in handy when using Sound on Sound Mode.

The ECCOS features advanced independent switching. The Delay or the Looper can be turned on and off independently. You can start the Looper without without a Delay Setting.

    I’ve had my ECCOS for a few months now and haven’t had much of a chance to use it until last week.

    I’m quite impressed with this as I was hoping for a looper that was easy to run and didn’t degrade my tone in any way. I’ve had several different Boss looper pedals and also have an EHX nano 360 on a different board. I was nervous as I wasn’t sure if this would be a better looping experience than the pedals I didn’t like (I haven’t had much luck with any looper pedal).

    The ECCOS is very easy to run as far as learning how to record, overdub and delete loops. Much easier than the Boss pedals I had. I struggled to use them and even thought maybe a looper is beyond me. Not so! A word of advice, the manual is your friend. You’ll be want to have it near when you’re first using this. It explains the pedal very well. One more thing, order the ECCOS remote switcher to go with it. I tended to hit both the bypass and tap button at the same time when I first got it. I ordered the switcher and it is the right size and the buttons are easier to use.

    Keeley Electronics, you did it again. Couldn’t be happier with this pedal. Great stuff!

    When I bought this, I was looking for a looper and most of the people I talked to said this is a great delay with a looper thrown in. The delay in this is awesome. Not like any other delay I have. The flanged trails are really cool sounding and I can see where I would like use this on stage.
