Everyone should learn some music theory, even if you only play a little as a hobby. It will improve your playing and understanding of what you are playing. I bought their bundle of Circle of Fifths, Chord Compass and Cheat Sheets. I used to play bass in bands long ago, and have been meaning to get back into it. I had a decent understanding of theory and the circle. But, out of site, out of mind, I wanted something to get me back where I was in that area, and possibly take me further.
These tools are extremely useful, They are built well, so are sturdy. They are designed well, allowing for an interactive experience for learning and using music theory.

Music is a multiple skill endeavor, physical and mental. I knew a lot of musician's that had the physical aspects, the mental was mostly knowing some chords and their names, and some fretboard notes memory. As good as they had gotten with that, once they started to learn even basic music theory, their playing improved exponentially. It may seem daunting to some, but it's really not. Like anything else, small steps, (No one learned higher level math without first learning addition and subtraction, then division and multiplication) These tools help with those steps. (The music, not the math ;) Though math is a factor in music, it's not the primary means for learning theory :)

It's not just the tools they provide with your purchase, they also include instructional books for understanding the theory and using the tools. I would probably only change one thing, in lieu of the current great packaging, I would prefer they were in a clear heavy-duty plastic envelope, to store the booklet and tool in. (They are sealed in a heavy plastic wrapper. which saved me from a poor delivery person who left them outside on the floor when it was raining, instead of a delivery box I have outside. Thankfully these are in a well sealed plastic packaging). If the packaging was using a reusable plastic envelope, they could still be sealed in thinner plastic to protect from moisture damage in shipping. But that's not a deal breaker, just a suggestion. The product is worth it either way.

If you play guitar or bass, you should get these. (They have piano products also, so I assume they are just as good. I'll find out when I start messing with piano. For now, I can only speak to the products I purchased. ;)

I've been playing for years and kind of gave up.
Well I bought these items and I've finally started to understand music theory in my 50s!

The best learning tools out there. Great what y’all are doing.

Highly recommend! Super easy to understand! Never have I ever seen guitar theory so simplified. Thank you!

Nice analog teaching tool, fits on a music stand

The book and Decoder are permantly on my desk so when I want time away from the screen I can dive in. This product is really helping to reinforce the fretboard visualisation and gain more of an understanding of how to form chords and experiment with triad shapes. My huge "Picture Chord" book remains unopened now as this product is way faster and encouraging trying new shapes and approaches that stay in the memory longer than trying to memorise 300 pages!

Might have to look at the Circle of Fifths and cheat sheets next

Within a week I've ordered the circle of fifths and chord compass. They are both great products for someone like me that has just started learning music theory.
Very fast delivery too, I would definitely recommend this company and their products.
I'll keep an eye out for any new stuff they may release in the future.

Great aid to music production

Noisy clan produces the no boilerplate guitar manuals every player should have! I love them and I use them daily for my practice.

So finally a product that gives me a clear insight to the circle of fifths amazing product

Whether you’re shopping for an intermediate guitar player or for a beginner, this book and decoder are great! I’ve been playing for 20 years and this thing still connected a lot of dots for me. A lot of “lightbulb” moments, if you know what I mean. I’ve since bought and suggested it to a handful of friends of all levels and they love it. It’s easy to follow for beginners and honestly, a better way to learn if you ask me. Easy to read and follow and not overwhelming like most instructive books or videos. Noisy Clan knocked this one out of the park.

The promo is accurate - this circle of 5th’s is the easiest to use (I’ve had several others). Easiest to read too, even in dim lighting. Excellent value. I ordered two extras for musical friends (birthday or Christmas gifts).

Great product and very easy to understand. Shipping is fast. I had an issue one time with receiving the product which was not the fault of noisyclan. The package was lost by the US postal service. Once I called noisyclan and told them about not receiving my order, joe immediately sent me a new set to replace the one I did not receive. Before, I could receive the new order, the old one was found by USPS and finally delivered to me. I advised joe that I would return the new replacement one he sent me since i got my original order. Joe let me keep it to share with a friend. Very much appreciated gesture. This is not a perfect world, things break, things doesn’t go as planned all the time. But customer service makes the difference. I will be monitoring noisyclan and I will be purchasing more products from them. Very happy with their high quality product and their excellent customer service.

Bought this and the circle of fifths compass. Incredible stuff. Yet more inspiring inventions from the homeland. Amazing!

I got my products very fast and are very informative. But for the price they come a little bit smash and wrinkled
