Get to know them!

Designed with the English independent record label Ninja Tune, the Erica Synths Zen Delay is designed to excel at one thing — creating the richest, dubbiest delay lines you've ever heard from a single unit. Combining a tempo-synced stereo delay line with a multimode 24dB synth filter, plus a tube circuit for analog overdrive, the Zen Delay is optimized to be used as a send/return effect from your console or DJ mixer. Complete with an extreme feedback range for endless dub echoes, and large, high-quality knobs that encourage hands-on interaction, the Erica Synths Zen Delay effects module is all you need to turn any track into a dub mix.

Legit dub effects without sacrificing mixer channels

Using the Zen Delay as a send/return effect from your mixer is fast and efficient, compared to the traditional method of creating dub-style delay lines. If you're not familiar with the technique, you would normally send signals from your mixer via aux output to a delay unit, and return that delay's output to a channel on your mixer. By returning to a channel instead of the aux return, you can then send the delay line back into itself to create extreme feedback (while also manipulating the channel's EQ and gain for creative effect). The Zen Delay packs an extreme feedback range, a gloriously rich multimode filter for tone shaping, and an analog tube drive circuit for harmonic enrichment, giving you all the tools you need for dub echoes without complex routing schemes.

Ample hands-on control

Dub delays are all about sonic manipulation — swelling up the intensity by turning up the feedback, tweaking EQs and filters to create timbral interest, changing the delay time for pitch effects, and so on. Sound designers at Sweetwater are pleased to report the Zen Delay effects unit is packed with high-quality knobs for hands-on control, including a tap tempo button for syncing your effects. You can even switch delay modes and filter modes at the flick of a knob, and once you've played with the Zen Delay for a bit, you'll probably be making tweaks without even looking at it.

MIDI and CV input for external control

The Zen Drive is perfect for hardware-based electronic music production rigs, and it's ready to integrate with other gear via MIDI and CV. Hook up a MIDI connection from your sequencer and sync tempos.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
