How to choose the best diatonic harmonicas
Tone
This isn't just about 'good' or 'bad'. We're talking about the fundamental character - does it have a warm, bluesy sustain, a bright, cutting edge for folk, or a more neutral voicing for cross-harp? Cheaper harps often lack complexity, tending towards a more one-dimensional sound.
Action & Responsiveness
How easily does the harp respond to your breath? A stiff action can kill your articulation and make bending difficult. Budget harps often have slightly rougher reeds and tighter tolerances, requiring more breath to get a clean note.
Durability
Plastic comb harmonicas are common at this price point. They're more resistant to warping than wood, but can impart a slightly 'plasticky' flavor to the tone. Metal combs are tougher but can transmit more vibration and noise.
Intonation
Are the notes actually in tune? Even slight intonation issues can throw off your playing, especially when recording or playing with a band. Expect some minor inconsistencies with cheaper models.
Bending Capabilities
Bending is a crucial skill for blues and many other styles. The reed design and overall construction impact how easily you can bend notes. Lower-priced harps might have reeds that don't bend as easily or predictably.
Buying guide
So you're looking for a decent diatonic harp without blowing your gig money? Been there. Plenty of folks start out thinking a fancy harp is the key to sounding like Sonny Boy Williamson, but a good player can make a decent harp sing, and a bad player can make a Hohner Marine Band sound like a strangled cat. This list is about getting the most 'bang for your buck' in the under-$100 range, covering what you can realistically expect for your money.
At this price point, you're making trade-offs. Don't expect Marine Band level craftsmanship. The plastic comb will be a noticeable difference from wood, and the reeds might not be as perfectly voiced.
Look for a harp that feels responsive and has a tone that you like - even if it's not the most complex. A little practice and careful breath control can go a long way in making a budget harp shine.

Questions
What's the difference between a Marine Band and a Special 20?
The Marine Band has a wooden comb, generally considered warmer and more resonant, but more prone to warping. The Special 20 has a plastic comb, more durable and resistant to moisture, but often a bit brighter and less 'organic' sounding.
Are plastic-comb harmonicas 'bad'?
Not inherently. They offer durability and are easier to maintain. They just have a different tonal character than wood-comb models. It's a matter of preference and playing style.
Can I record a cheap harmonica and have it sound good?
Absolutely, but you might need to EQ carefully to tame any harshness or muddiness. A good preamp can also help bring out the nuances. Mic placement is crucial.
Which key should I buy?
C is the most common and versatile key to start with. It's used in countless recordings and lessons. After that, G is a very popular choice for cross-harp playing.
What does 'cross-harp' mean?
It's a playing style where you play a harp in a key different from the backing band. For example, playing a C harp over a G backing track. It gives you access to different notes and a bluesier feel - but it's a bit more advanced.
