@lillycoyote the mini’s are really charming! But because it covers only one octave it’s tough to play much more than simple tunes on it.—I have a minor key mini I use to hail my companions when hiking or skiing. It’s a hoot and way more than nothing.
Note that most of the time people are using ‘diatonic’ tuned harmonicas. That tuning has the disadvantage of missing a couple notes from the ordinary scale, but the advantage that adjacent notes are always compatible on blow or draw.
Hohners are very popular and plenty of professionals still use the MarineBand and BluesHarp models with the wood comb between the holes. You can get a classic blues sound out of these easily.
There are all sorts of problems with the wood comb styles. Those harps are toward the lower end of Hohner’s offerings and the reeds are not the highest quality. You may find yourself doing frequent maintenance on the reeds to keep them working, especially if you really wail on them. But that’s hard to do and you can end up getting a new one regularly.
I find the wood combs annoying because they swell and distort a bit with (inevitable) saliva so they can lose the seal between notes and they can stick out a bit and tear up your tongue and lips.
In the Hohner line my favorite is the Special20, which is in their MarineBand line but has a plastic comb and superior reeds. A lot of pros will use these for those two reasons.
Some folks like the Hohner CrossHarp, which has the added advantage of reeds that seem to stay truer to the note and replaceable reed plates, but it is just not as loud as most harps and it’s hard to really wail a note out there with one of these.
There are a few other makers of popular harmonicas. I have several Lee Oskar which not only have a great sound, they are built so you can replace the reed plates if needed… so you don’t have to buy a whole new harp. I have changed out the plates on my G and C harps multiple times.
Suzuki is emerging as a good brand lately. Some of my favorite YouTube players are using these all the time. I don’t have one of those yet but I have an Overdrive. Not only is it an exotic tuned-port style (you have to hold it carefully to avoid blocking the ports), the one I have is a low-F, and the thing really puts out a great low sound.
