Hi-fi Looper Pedal with 6 Minutes of (Stretchable) Record Time

If you’ve been searching for a simple looper with bulletproof durability, supreme sound, and room for expansion, MXR’s Clone Looper is the pedal for you. The Clone Looper boasts sample rates up to 88.2kHz — nearly double that of many other digital looper pedals — so you won’t encounter aliasing when recording an overdriven electric or a percussive acoustic. You get up to six minutes of record time to share between unlimited overdubs. So whether you’re creating a 6-minute play-along track or 30 seconds of cascading melodies and harmonies, the MXR Clone Looper has you covered. Your loops stay in the pedal between uses, even when you power it down, so it’s easy to take ideas from home to the practice space for fleshing out. Advanced features, including 1/2–2x time stretching, expression pedal and tap switch inputs, and Play Once mode for backing tracks give the MXR Clone Looper plenty of room for you to grow. It’s all set in a brushed metal housing with an impeccable all-analog signal path, with programmable true/buffered bypass switching to suit any pedal setup.

What’s Cool

Flashing 4-count entrance

Wanna make sure those rhythm parts come in right on the downbeat? The MXR Clone Looper gives you four flashing lights at the beginning of the loop, so you never miss an entrance.

Six minutes, unlimited layers

MXR’s Clone Looper gives you six minutes of record time at an unprecedented 88.2kHz sample rate to capture the smallest details in your performance. Those six minutes can be split between a 6-minute single layer or 100 layers at 6 seconds each.

Impressive build and audio quality

The Clone Looper’s analog through-path is set in a handsome brushed metal housing with rugged switches and jacks. Toggleable true bypass and buffered bypass switching will make this looper fit into any pedal setup.

Hands-free time stretching

Looking to get the most out of your Clone Looper? Connect an expression pedal (e.g. Dunlop DVP3) or tap switch (MXR Tap Tempo Switch) for hands-free control over loop speed. You can shift tempos dynamically, from 1/2 speed to 2x speed*, just by rolling your foot or tapping in playback speed. You can even reverse loops for some pretty dramatic effects.

Note: 1/2 speed increases record time to 12 minutes. 2x speed decreases record time to 3 minutes.

Play Once mode

Got a cool one-shot that appears several times in your set? Set the Clone Looper to Play Once mode to activate sounds or re-trigger them with DJ-style stutter effects.

Simple controls

We at Sweetwater found the MXR Clone Looper to be easy to dive into, with dedicated footswitches for record/dub and play/stop and an undo feature for overwriting the most recent loop.

I love my MXR Clone Looper! THANK YOU SWEETWATER!

I LOVE THE PRODUCT and am extremely grateful for how Sweetwater made me feel on my first product purchase. MEGA KUDOS for Codie Priester! Cody took the time to call me directly and let me know he had my order and it was ready to ship. I was shocked and surprised to get this kind of personal touch from the company! On top of that my order even had THANK YOU CANDY! My order arrived in a timely fashion and included ample information, orienting me about Sweetwater's support! That was awesome to know one can count on the company to be there by you. I did find a need for a better instructions on how to use this little gadget, well after a few tries I figured it out, but I am sure now if I would have called, Cody would have advised me. THANK YOU SWEETWATER FOR THE AMAZING SERVICE AND SUPPORT.

Two buttons are the way to go!

I upgraded from a single-button looper because the double-tap was tripping me up too much. This is perfect. Being able to start the loop/overdub with one button and stop it with another is huge! If you're using the same loop at various points in a song, being able to seamlessly stop and start it is essential. The Clone Looper allows me to do that. I was concerned that I might unintentionally depress the volume knob (which is also a pushbutton switch) with my foot while operating the buttons, but now that I've been using it for a while, this has not been an issue. It is far enough away from the other buttons. As for the speed and reverse functions, I have not used them, so I cannot provide any feedback on those.

I'm Loopy!

Tried getting into the loop - pun intended- with my Boss VE-8- but didn't like the double tap needed - saw people liked this one for its simplicity and features - I'm still on the learning curve but am confident this was a good choice for me.

The Sound Quality Sales Pitch is for Real, the Clone Looper Sounds Fantastic

OK, so my ears are retirement age and have weathered the assault of playing in loud rock bands and other deafening environments (USAF and oilfield), but my loops on this thing sound great to my ears. I bought a used Clone Looper at GC so I could return it easily if I didn't like it. I'm using it to work on original music in the hopes that the jam band I'm in can get back together. A Bongo bass, neck pickup, bass EQ up, highs rolled off through my too-huge pedal board (only using the EQ) sounds amazingly, glowingly warm through the Pignose Hog bass amp I'm using as a practice amp. The playback from the Clone Looper captures all of this glowing warmth beautifully. I'm very impressed.
Music background: LIfelong hobbyist. I should be better considering how much I practice.

Excellent Looper

The new MXR looper fits my needs perfectly for solo acoustic guitar performances. Easy to use and built MXR tough! It even looks cooler than most stomp pedals!
