A unique, beautifully mellow sound, based on a revolutionary concept: the Special 20 was the first diatonic harmonica in the world with reed plates recessed into the comb, creating a projecting plastic mouthpiece. This makes it more comfortable to play, and the most copied harmonica design worldwide. Its distinctive sound is perfect for everything from Folk and Country to Rock and Pop. The Special 20 offers everything a professional harpist needs, but it’s also the ideal beginner’s instrument thanks to its smooth playability and comparatively affordable price. If you’re not just looking for a companion for the first few steps, but one to take you all the way, the Special 20 is your best possible bet.

  • The reed plates are recessed for a more comfortable mouthpiece
  • Reliable performance under all climate conditions thanks to the resilient plastic comb
  • The cover plates have a small back opening to highlight the warm sound

happy with the sound, quality product


Purchased as a first instrument for a musically talented child. Parents are extremely happy with the sound. The child is really taking to it! Quality product.



I definitely recommend the Hohner harmonica !5 stars


Great handy musical instrument. My first and I highly recommend



At 5 and counting...


As a guitar player who adds harmonica when required, the Special 20's have offered an ease of playability and have been durable from the over-blowing that novices are often guilty of. Unless you are a wizard virtuoso of the harp, these get the job done.



Yes I would highly recommend this Harmonica.


I bought the harmonica for my grandson. He loves it. He learn Billy Joel's song right away. It's great.



Special 20 rocks!


I have been a fan of the Lee Oskar harmonica until I tried this Special 20 by Hohner. The Special 20 plays as well as any harmonica I ever tried. It has a nice feel in my mouth and the notes are sweet. I would not hesitate to recommend this harp to any player wishing to upgrade from lesser models.



I wouldn't have any problem purchasing this product again.


I'm just a beginner at the harmonica, but I'm very happy with my special 20 that I purchased from you.



One of the Best Blues Harps Out There


To be frank, I have only tried two different diatonic harmonica models: this and a Chinese-made harp from Mud Puddle. The former is clearly better than the latter, in my opinion. I have been playing these Special 20s since December 29, 2018 as a self-taught blues harper and these babies are tough as iron nails. What I meant by that is that for practice from 10 minutes to one hour each day, the harp is just a workhorse. The pitches for each hole on both reeds don't go flat and it still retains its responsiveness. As for the harp itself, in terms of what makes it famous, the response is astronomically good and it's very air-tight despite the rasp in its timbre. For its comb, it's actually fairly smooth even though you can cut your lip on it sometimes. Despite not being known for this next part, I just want to give this away. The Special 20 may have the best timbre for any diatonic harmonica. This may be controversial, but let me explain. Since the inception of the internet (as far as I'm concerned), this harmonica's timbre is described as being mellow and/or sweet. I never saw where they were coming from. From the Special 20s that I've played so far (C, Bb, and Ab), they all had a warm, powerful sound with a raspy tone. That raspiness is often overlooked, but it gives the harp a distinct and dark timbre that is just made to play the blues. Just a heads up that the bends will sound growly at one point or another. There is only one other gripe I have with this harp which isn't the comb. My Bb has a slightly angled top cover compared to the other two. Which had me make a "conclusion" that some of them look rushed. However, my Bb played extraordinarily well and is my favorite key for the Special 20.

Good Harps, good price


I like the plastic comb; Special 20 is a good all-purpose harp. I play guitar and harp (keys A,C,D,F,G): country, folk, blues, pop, Cajun and zydeco. Eventually I blow them out and have to replace them. I understand they can sometimes be repaired, but I've never been good at it, so I look for deals -- buying the package of 3 saved about $15. Cheaper harps aren't worth getting.

A Gold Standard


The SP20 is one of the gold standards in diatonic harmonicas, but they tend to have quality check issues coming out of the factory. Often you'll buy one out of the box that has flat notes, or gets flat very quickly. The latest one I bought was like this, and when I took it apart to tune and gap it, the draw reed plate was discolored! And the cover plates were put on slightly crooked too. Jeesh. But hey, I still love the sound and tone, so I come back for more. Also note that the SP20 isn't as durable as the Lee Oskar (another gold standard), so you might find yourself replacing your SP20 more often. A big issue many have with the SP20 is the sharp comb edges. This becomes a pain when you're playing the 1 and 10 holes. Handy players will usually round out those edges with their tools. Lastly, something to consider is the tuning. The SP20 is JI/compromised tuned, while the Lee Oskar and Golden Melody are ET tuned. This does make a difference, so try out both. People generally say that JI strikes a good balance between single note lines and chords, while ET is mainly good for single note lines.
