Hello, Emanuel

I'm afraid I have no experience with that mic so I can only make general comments. 

With any mic, several factors "matter":

 1) Impedance - is it high or low impedance? This doesn't mtter for tone, but understanding what it is to correctly connect it to an amp, pedal or PA does matter.  Impedance or wiring mode mismatches can cause changes in tone as well as reduction in output.

2) Shape - the ergonomics of a microphone matter - because our ability to cup a mic effectively has a HUGE impact on the tone of most mics. Diameter, weight and shape all matter. Looking at pictures of this mic, it looks to me like it may be OK in this regard but on the heavy side. However if those ridges make it hard or uncomfortable to cup, that would be a strike against it. 

3) Frequency Response - as microphone manufacturing and materials technlogy have evolved, high frequency response has increased. That means newer mics send more high frequency content to our amplifier - and that can be perceived as overly bright or harsh tone. Older mics' high frequency response tends to fall off sooner, which is why harmonica players crave vintage elements. (Really good cupping helps to diminish the high frequencies, though, so a pro player often WANTS more high frequency response, as that gives him or her a wider tonal range.)

4) Headroom - this is the ability of a mic to withstand high sound pressure levels without distortion. A kick drum mic has to tolerate very high sound pressure levels without distorting - consequently it might not make a great harp mic if you want to be able to get the mic to "break up" (distort) when you play hard/cup tightly. As a rule, older mics have less headroom than newer mic designs.

In the end - only one thing matters. Do YOU like the mic? Most of us tend to like ANYTHING new to us. Human beings like change, especially if they paid for it! So whenever I judge a mic, I not only listen to it - I A/B it with mics I KNOW I like the best. I hope that helps!/Greg
