BEST piano mic system ever!
Look, this mic system is the best investment I have ever made in my life! It made me fell in love with my grand piano again and again. Honestly, it is the biggest incentive I have to better my skills and produce high quality value for my YouTube channel and Spotify. I absolutely love the 3d stereo sound image that it creates; the balance is perfect, no need to EQ the recordings, it captures every single piano overtone (!!) and it does offer the most realistic, warm and detailed piano sound I've heard after spending more than 3 months+ researching. I'm still in awe that it virtually has no bleed. Earthworks couldn't do any better. I simply cannot imagine using any other mic system in the future, ever.

Here's a sound-demo video where I showcase my 10 reasons why this is the best mic system in 2022 and beyond. :)

A must have for pianos!
Have tried several different microphones and rigs since 1998 for our grand piano and this is truly the best. The installation was easy and fast. We are using the microphones in a live setting with drums, percussion, and guitars and the microphones are not picking up bleed over from other instruments. These microphones provide the best sound and clarity of your piano without having to overly EQ it or build a rig. If you have a piano and you are struggling to hear it or want something with more clarity this is what you need!

Just buy them already
Incredible and detailed sound with a clarity you can't get from traditional mics. Got these a few weeks ago, already made one video and two recording with them and they sound phenomenal. Seriously just get them already they're worth it.

I'm a trained pianist at the doctoral level, teach at a university and work as a producer making ad/tv music. I recently got a 9 ft yamaha concert grand in my living room and these mics are better than anything I've used in the past (Neumann, Schoeps, etc). They are obviously a close mic sound so it won't be like hanging mics (which I never liked anyway). They do a good job of avoiding bleed and can really change depending on how far down you place them on the strings so there is some flexibility for sound. I might add a room mic to get natural reverb.

But the biggest thing for me is how they are always set up and ready to go with perfectly positioned mics, nothing kills me more than long setups I tended to use a vst just because it was easier.

Works for me.
My favorite piano mic system!
In my opinion, this is the piano mic kit out there. If you do any kind of recording on a regular basis with an acoustic piano, you'll love how conveinent this mic system is to rig, and how great it sounds no matter the room it's in or instrument you attach it to. I like the SKB hard case that the mic system lives in, and all of the components are high quality and mostly robust.

Things to be aware of with this kit..
- The connection cable to the DI box is a bit fragile, so handle with care! I think the second version of this kit (comes in the silver box) has a better connection cable design.
- People tend to not see the mic is in the piano, and stage hands or enthusiastic talent will push the piano with the mic bar attached and not realize it! A testament to it's low profile.
- The mic system gets in the way of extended piano work... I usually opt for DPA 4099 or 4061 kits when extended technique is on the program.

This mic system is amazing! It's the best sounding set of mics for piano recording I've ever heard. The recording sounded exactly like the piano did live. If you have a recording studio or you have a piano that needs to be mic-ed, this is the ultimate sollution.
