Great idea, great sound Great value

This is a beautifully made, perfectly tuned, and nicely set up for overblows, double Richter slide harmonica in A/Bb. It's airtight and has great tone. The bends work well out of the box. So do the overblows but a little twinking is needed for my personal use. Your mustache will get caught if you don't trim it though.I can't imagine why everyone wouldn't want one

Bad taste

Great harmonica but tastes a lot of slide oil. I can't play it without getting this bad taste in my mouth. The richter tuned one I ordered previously didn't have this problem. I'm airing it out so I really hope this helps.

A new generation has arrived

I bought the ‘pop’ version in the key of G because I like ‘paddy richter’ tuning and a relatively low pitch. It is in tune, sounds fine, and is much easier and more comfortable to play than other chromatics I have owned. I also like its relatively small size. I suggest that anyone interested in purchasing the ‘pop’ version should carefully study the chart showing how the notes are laid out, particularly regarding the first four holes. If you have become familiar with other harmonicas, whether diatonic or chromatic, some re-learning will be required for this instrument. I don’t know how suitable it would be for playing chords.

Revolutionary design and great instrument

Just got the Richter tuned in A. This is an amazing instrument. It's super fun to play, air tight and the slide opens up a world of possibilities I couldn't do on a standard ten hole diatonic without overblows. I will definitely get more keys.

Enhancing richter tuning possibilities

This Harmonica is one richter tuned harp and with a button press another richter tuned harp a half step difference. Not chromatic, but a lot more chromatic possibilities. You can get a lot of notes with the press of a button that otherwise require over blows or over draws. I’m just learning my way around. But it is fun and interesting.
