A fantastic entry level chromatic harmonica
After playing diatonic harmonica for several years, I wanted to explore chromatic to facilitate playing jazz. While I can overdraw and overblow, it's not quite the same. I found the ergonomics of traditional chromatic harmonicas, particularly the hole spacing and overall size, somewhat awkward after trying a few. The Trochilus, being closer in size to a diatonic, immediately felt more comfortable. I specifically chose the C6 solo tuned model due to its bebop tuning, which modifies the 4th blow from the root to the 7th (C to B in this case). This provides a flat 7th on the blow slide and avoids having adjacent root notes on the 4th and 5th blow. Instead, the root is on the 4th draw slide, which feels more intuitive. Playing the Trochilus feels very similar to playing a diatonic, though the tone has a brass-like quality. The reeds are responsive and easy to bend, the body is air tight and the slide action is smooth. It played perfectly right out of the box without any need for reed adjustments, and its metal construction feels robust. Despite the metal comb, I haven't experienced any teeth clinking, although I have occasionally caught my lip in the slide. Overall, the Trochilus is a highly playable chromatic harmonica that delivers on its promises. I would recommend it to anyone looking to venture into chromatic playing or simply seeking a musically expressive instrument without a high price tag.

Small 10 hole harp with a switch for added fun and great sound. Very very good build quality.
I have a lot (and I mean a lot) of harmonicas.. Tremolo, Diatonic, Chromatic.. interesting spins and edits on reliable platforms from various brands. I play a better diatonic 10 hole than I can with the others but I love the chromatics too. When I saw and heard some of what the Trochilus can do, a diatonic with the slide of a chromatic with the ability to bend and overblow I was floored.. so I picked one up. The blue richter tuned model- in the key of G. My goodness this is a nicely weighted, nicely built, airtight and small enough for a pocket, instrument. A new favorite after playing for just about 1/2 hour. The case it comes with is similar to an eyeglass case, with a soft covering and spring steel 'snap' when you close it. If you enjoy quality sound in a small package, versatility, and good value for your money then I think you might want to give this a try. A Beginner should be able to learn and play this well- holes are of good size and it doesn't require a lot of force to make sound. The comb is plastic but the body is metal and the slide and mouthpiece is metal. Switch works smoothly with a bit of a damper to keep it from clicking.

Easy and Comfortable to Play
I hadn't played a harmonica in a few years and decided to get back into it. Since I didn't know what kind of music I wanted to play, I opted to get an upgraded Marine Band, a Trochilus Solo, a Easttop Performer Chromatic, and an Eastar Admiral Tremelo. After two months of playing again, I think my favorites are the JDR Trochilus and the Eastar Tremelo. Why? They are both easy to play, small and comfortable, and both sound great. The Trochilus easily bends notes and plays like a small diatonic. I never use the Marine Band. I think it's a good introductory harmonica for someone who plays diatonic but wants to learn chromatic. The big Easttop I bought has three octaves and has a very nice midrange sound, but the airflow resistance is not consistent, the holes feel a lot farther apart, and it really takes more effort to play, especially if you are trying to play it quickly. The little Trochilus is just so easy to grab and play well. For the price, I think it's a very good value.

These are great harmonicas.
These are great harmonicas and in many ways they are a game changer. I like playing melodies on a diatonic, but even with modest proficiency of bending and over-blows, there are many notes still impossible to find on a standard Richter tuned harp. This harp bends and over-blows quite well right out of the box and gives you a dozens of extra notes when depressing the key. You can expand your range without loosing the bluesy sound. I have purchased 4 different keys now. These are a high quality harp, loaded with cool new features and is a good value. My only issue is I need to modify my harmonica case to accommodate its slightly larger size.

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

Mostly nice, bu not quite as advertised
This is a bit of a mixed bag. It has a comfortable weight, the quality of the materials seems high. And it seems to be put together well It feels pretty airtight and plenty loud. The reeds are bendable and the slide works well. For me, at least, the odd shape of the harp is very comfortable and makes the slide a pleasure to use. Why only three stars? Two reasons - one specific to the Paddy/pop tuning. First: The reeds are overall not tuned very precisely (they seem to be aiming at 442) but individual reeds run from 10 cents flat to 20 cents sharp, producing some remarkably ugly chords. Second: Unlike the Richter and Solo tuned versions, pressing the slide on Paddy/pop version does not always raise the note by a half step. On 2-draw is flattens the note by a half step and on 3 draw it flattens the note by four (!) half steps. I'm expect that there is a reason for doing it this way (it certainly makes the Gm scale on a G harp very fluid) - but it is effectively undocumented. There is a (largely in Chinese) paper insert with the harmonica that documents this - but this is only after purchase and then only if you get out a magnifying glass to read the small font in black on dark magenta. If I were confident that the tuning of the individual reeds had been addressed I still think that I'd be happy to recommend it - but it should be much easier to find out how it is tuned before purchase.

ich bin (Laien- und Hobbyspielerin) begeistert, alles was ich mir bei chromatischen Mundharmonikas gewünscht habe, ist hier realisiert worden: Leichte Ansprache, 12 Kanzellen reichen mir, keine Ventile, gut zu pflegen! Auch Paddy und Blues kann ich nur empfehlen

mine was not tuned properly out of the box. always feels bit off with a 10 hole chromatic IMO

Un'armonica blues con il registro per ampliare le note naturali. I bending tradizionali di un'armonica diatonica riescono bene e facilmente. È possibile eseguire note aggiuntive con il registro, come gli overdraw (dal settimo al decimo foro), che a me non sono mai riusciti. Ottimo rapporto qualità/prezzo ... Soprattutto per l'acquisto fatto durante il periodo del Black Friday

I got C harmonica with solo tuning. Very pleased with it. Airtight and well made at a very reasonable price. I already have two and would recommend.
