NuX MDD-7 Tape Echo Review – Capturing the Spirit of the Space Echo on a Budget
If you’ve been hanging around the guitar world for any length of time, you’ll know that certain effects achieve a kind of cult-like status. They aren’t just tools for making music—they become legends in their own right. Few effects embody that mystique quite like the Roland Space Echo.
The original RE-201, and its descendants, have long been worshipped by guitarists, producers, and tone chasers alike. It’s a tape echo machine that delivered not just delay, but atmosphere, warmth, and vibe. When I first started getting into pedals, the BOSS RE-20 (the digital twin pedal that captured the sound of the Space Echo) was already discontinued and widely considered a grail pedal. The mystique only grew from there, with whole communities of guitarists swearing by it as the gold standard for ambient delay.
BOSS eventually answered the demand with two modern versions: the RE-202, which aims to fully recreate the Space Echo experience, and the smaller RE-2, which brings that character to pedalboard-friendly form. Both are fantastic, but both come with fairly premium price tags.
Somewhere in the middle of all this, NuX quietly dropped their own take on the Space Echo sound: the MDD-7 Tape Echo. I’ll be honest—I’ve never been one to get swept up in hype. In fact, I usually head the other way from it. When people online start describing a piece of gear as “life-changing” or “essential,” my instinct is to push back. Surely no pedal can live up to that kind of status?
And yet, after spending some time with the NuX Tape Echo, I get it. I finally understand the appeal of the Space Echo sound.
What is the Space Echo Sound?
At its core, the Space Echo was a mechanical tape echo unit with a built-in spring reverb. That might not sound particularly groundbreaking by modern standards, but the way those two elements interact is what makes it so special.
The tape delay itself is naturally imperfect. The repeats degrade over time, with a bit of wobble and modulation creeping in as the tape runs. Add to that the warm, slightly unpredictable spring reverb, and you’re instantly transported to the sound of vintage records. Huge, expansive echoes, swirling with character, that somehow feel organic rather than clinical.
The NuX Tape Echo captures that beautifully. The moment you plug in, you’re hit with lush repeats that shimmer and wobble in just the right way. Pair that with the characterful reverb, and you’re living inside classic ‘70s guitar tones. If you’re into players who used ambience not just as a background effect but as a key part of their sound, you’ll feel right at home.
Controls and Tone Shaping
One of the standout aspects of the MDD-7 is just how much control it gives you. It’s not just a one-trick pony; it lets you dive deep and sculpt the sound exactly how you want it.
The EQ section is particularly powerful, with separate Treble and Bass knobs to shape the character of your repeats. Personally, I prefer delay to sit behind my dry guitar tone rather than fight with it. Pulling back the treble slightly allows the repeats to melt into the background, almost like a reverb. It thickens and fills out the sound without dominating it.
On the other hand, if you want your delay to be a key part of your sound—think The Edge from U2—you can push the treble up, cut a bit of bass, and suddenly your repeats stand shoulder-to-shoulder with your guitar. Pair that with the Level control, and you can blend the echoes to sit exactly where you want them in the mix.
Of course, you also get the standard delay controls you’d expect: Time for setting the delay length, and Repeats for dialling in anything from a slap-back to a self-oscillating wash. There’s also a dedicated Tap Tempo footswitch, which is a must-have if you want your delay to sync tightly with a song.
The Select Knob and Delay Patterns
Where things get really interesting is with the Select knob and the small LCD screen. This visual element displays three playback heads, representing different tape delay patterns. Depending on how you set it, you can get single, dual, or multiple rhythmic repeats—including dotted rhythms that immediately conjure up iconic guitar tones.
This makes the pedal feel more like an instrument than just an effect. You’re not just adding echoes—you’re creating rhythmic textures that interact with your playing. Whether you want subtle depth or a cascading wash of ambience, the Tape Echo can deliver.
Spring Reverb Built In
Another highlight is the built-in DSP spring reverb control. Spring reverb has a distinctive character—it’s splashy, it’s drippy, and it screams vintage. On its own, it’s fun. Combined with tape echo? It’s magic.
Adding just a touch of spring can transport your sound straight to a smoky club in the ‘70s. Push it further, and you’re in full-on surf rock territory. It’s not a pristine studio reverb, and that’s the point. It’s vibey, imperfect, and dripping with character.
Hidden Features and the Editor App
True to NuX form, the Tape Echo doesn’t stop at the obvious features. There are hidden parameters tucked away for players who want to go even deeper.
Hold down the Select knob, and you’ll unlock controls for Wow, Flutter, Saturation, and even a Kill Dry option for running in parallel setups. These secondary parameters give you the ability to really fine-tune the tape character—whether you want smooth, stable repeats or unpredictable warbles that feel like your tape machine is on its last legs.
For those who don’t want to scroll through menus on the pedal itself, NuX offers an editor app. The app gives you access to all of these parameters in a clean, easy-to-use visual format. It’s intuitive, it’s quick, and it makes experimenting with sounds much less intimidating.
Add in the ability to hook up an expression pedal, and you’ve got even more flexibility. You can assign it to control time, repeats, or level, making the Tape Echo a powerful performance tool.
How Does it Stack Up?
Now, the obvious question: how does this compare to BOSS’s RE-2 and RE-202? Honestly, I can’t say for sure. I haven’t spent any time with those pedals so it would be unfair to make a direct comparison. What I can say is this: the NuX Tape Echo costs less than the smaller RE-2, and yet it offers a serious amount of control and flexibility.
It’s not necessarily aimed at beginners. The wealth of features and tweakable parameters might overwhelm someone who just wants a simple delay. But for players who love to get lost in sound design, or who want to add a very specific vintage flavour to their rig, the Tape Echo hits a sweet spot.
And that’s really the point. It’s not just another digital delay. It’s a love letter to a legendary sound, made accessible to players who don’t want to spend a fortune chasing it.
Two Cents
I’ll admit it: I used to roll my eyes a little at the hype surrounding the Roland Space Echo. It seemed like one of those things guitarists romanticised because of its rarity and vintage status. But after playing through the NuX Tape Echo, I get it.
There’s something about the combination of tape-style repeats, modulation, and spring reverb that just works. It feels lively. It feels organic. And it instantly transports you to another era of music.
The NuX MDD-7 Tape Echo isn’t the cheapest pedal in their range, and it’s not the simplest either. But it’s one of the most characterful, and one that rewards exploration. If you’re a guitarist who loves ‘60s and ‘70s tones, or if you’re chasing ambience with a vintage flavour, this one is absolutely worth a look.
