This is a really good sounding harmonica microphone, and at a really affordable price.
Bought this as a starter mic for playing harmonica, but comparing it with a friends Green Bullet I actually prefer this one.
Have no idea how sturdy it is, the casing being plastic, but as long as you don't drop it a lot I guess it's fine. Cord and volume knob feels solid.
It is somewhat bulky and heavy, which is the downside of it. I have big hands so it's ok for me, but for someone with small hands the size of it may present a problem.
Would have preferred detachable cord, but fixed cord seems to be standard on harmonica microphones so I guess it is what it is. On the plus side the cord won't fall out mid-playing...
Sound-wise it's got that honky tone that's appreciated for harmonica microphones, which feeds well into both clean and overdriven amplification.
I recommend this thing to anyone wanting to start off playing amplified harmonica. At this price You can buy it untested. But before replacing it with another microphone - try different ones, as You may choose to keep this one...
