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.

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.

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.

Knowledge from a pro
Okay people, this is a pretty good harmonica. I returned it because it's too tinny for my ears. It has a brassy sound, not warm and pleasing. Still it's one of the better tuned harmonicas. But first ask yourself why the interest in harmonicas? It's usually starts out, to experiment with as a fidget for a hobby. That can lead to an interest in music. It should be noted, that harmonicas are set up similar to that of a guitar in that they use chords. Harmonica's play chords (rolling chords to be exact), so you really don't have to be very good to sound good. Why, because chords sound good. If you blow or Draw from any single hole you can get a single tone like that of a piano. As far as composing music, that takes skill and let's face it, nobody wants to hear a record or CD with somebody's harmonica playing on it. That won't sell records. But it's a lot of fun for the person holding the harmonica. The other thing you can do with a harmonica is to buy a harmonica book that instructs you to play music designed for harmonicas. You can't play all music obviously, but it means you can impress your friends and you don't have to know anything about music to do it. These books are quite good. The problem lies in that any harmonica you get won't be into tune or balanced very well. BECAUSE THE MANUFACTURER JUST CAN'T SPEND THE TIME TO DO IT, SO ALL YOU GET IS A HARMONICA THAT IS IN THE BALL PARK, BUT IT'S NOT BALANCED OR CORRECT EVEN IF ALL THE REEDS SOUND. So therefore, you'll have to get an education and tune it up yourself. Don't even think for one minute that no matter how much you've spent $500 or above that the manufacturer will do much to put your harmonica in tune, even under an ironclad warranty. Fact, They just won't. YouTube is excellent for advice on Reed justment, and if you don't do it, your harmonica or any harmonica Straight Out of the Box won't sound very good, (factually just give it to a child and then put up with the noise of a 2-year-old). But if you take the time and do the work your harmonica will be professional and a delight to play. It's a remarkable improvement, and you'll get good at adjusting your reeds after you destroy a few harmonicas learning the Craft. Tools needed to do this type of work, a highly professional reed gapping gauge, i.e. Simply use a 3x5 index card, honest that's all it takes. Now you'll need a few Jewelers screwdrivers. And I use a flat plastic toothpick to adjust the gap for blow and draw reeds from the top side of the frame. Important, do not disassemble the frame which is attached to the plastic comb of the harmonica, rather use one of the finer Jewelers screwdrivers for regular head screws, and place the screwdriver in the mouthpiece hole to raise or lower the Reeds from the underside of the frame that is still attached to the harmonica comb. Important, this is delicate work, when making adjustments keep in mind all of these adjustments are very small. Nothing to aggressive. All it takes is just a little bit, going too far can make it much more work to readjust it, and over bending a reed can weaken or break the Reed. I hope this helps.

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

BLOWN AWAY!!!!!
Wow, I'm an advanced player. I have played chiefly Honer and a few Suzuki Manji diatonic in their Minor Keys. Of the Honer, I love their Crossover. I have been playing them for ten-plus years. There Bamboo combs are very good. But, Honer! You have some very, very, very serious competition with this Trochilus Harp that is Richtor tuned. All the things that I could point out that I don't like about the harmonicas that I have and have played are eliminated with the Trochilus! It plays as loud as the Crossover, the comb is designed for comfort as well as tone. It's super Air-tight. Absolutely beautifully made! Very nice case. It is so easy to play. I'm now playing riffs and runs I could not play on the Crossover's. It's got me back practicing again! I don't give out 5-star reviews very often, But this instrument truly warrants 5-Stars! Beginner or Pro!

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.

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.

Trochilus Mundharmonikas Bb & C
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

Ottima armonica per il prezzo proposto
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
