I would love to see a 4 unit rack version of this with the "Variable Impedance" knobs on the front as well as the DI jack and HPF/Gain switches. I use one of these for acoustic guitar/bass DI with a Manley or Neve pre and it sounds fantastic, better than the mic pre stock DI's as it is matching your impedance. Also great with an SM7B.

Highly recommended.

Simply stated, you can dial in the sweet spot with variable impedance, optional low cut, with 3 gain settings on a mic or DI. Now you can use that ribbon mic on a low gain tube amp. Badda Bing

My favorite musical tools are those that sound great, are easy to use, and don't cost a fortune. The cloud lifter Zi is just that kind of tool.

Your ears will tell you immediately if you have hit the sweet spot. After that forget about it, you are in sonic heaven.

Other companies sell products that don't allow dialing in on the sweet spot. Yes you can manipulate signal in the box but, why bother when you can

get the signal right at the source. I've picked up two of these and am very happy with the results. Teve Smith (engineer) gets kudos for bringing this fine product to my attention.

Thanks Cloudlifter!

I've purchased 2 because one wasn't enough. If you want to control tone at the front of the sound chain this is the box for you. Solid construction and great for getting your tone just the way you like it.

I've only had this little wonder worker for a few weeks, but it's been incredibly useful for vocals, particularly when used with passive and ribbon mics. I wish I had a camera to record my face when I turned on the phantom power with my old ribbon microphone. It was a weird experience, let me tell you.
Anyway, I've also found it incredibly useful in recording guitar with plugins. The impedance dial is really very handy in this capacity, as is the roll-off switch. I've even used it to boost the output from my beloved Mellotron to good affect.
The build quality is absolutely top-shelf. Look forward to years of use and experimentation.

I was looking for some type of device that could let me "shape" the sound of my electric guitar.
My Sales Engineer, Ben Robinson, suggested that I get a Cloudlifter Zi with Variable Impedance.
I didn't even know what any of that meant, but I bought it and am very glad I did.
I record my guitar out of a Fender Princeton Reverb amp, using a newly-purchased Telefunken M81 mic.
Whoa! What a difference in tonality!
You really can "shape" the sound of your guitar.
Since this only works on dynamic or ribbon microphones (as far as I know, and I don't know much), I decided to record my voice on it.
I wanted to mimic the sound of an old-style radio broadcast.
I just cranked the output on high, set the Impedance at 1.4, and got exactly the sound I wanted without having to add any plug-in effects from Logic Pro X.
I love this device and just wish I had bought it sooner.
Also, when recording guitar, you can really make your guitar sound smooth as glass, or crank it up and get some great effects.
I hope this is helpful.
Cheers.

I've purchased a lot of music equipment over the last 45 years. This is my easiest 5 star rating. It does exactly what it says and gives you total control of the end result. I do have a future wish list item: add footswitch control for adjustments. As a solo performer/engineer/producer, it would be easier to dial in sound while singing, playing if the adjustments could be made by your foot rather than your hand. I would certainly buy one of those and hang on to the original!

I have several of the CL-2, and the difference they make is Fantastic! You will be amazed at how good the mics you already have can sound. (But you will still want new ones... we all do.) Can only imagine what the variable impedance can add.
