Mini mic

Hi Greg

I am looking for some kind of a mini mic (with a size comparable to the ones you fix on a shirt) which I could fully 'envelop' together with my harmonica in my hands. My intend with such mic is to better capture the full sound of the harp es well as the results of handtechniques such as Wah-wah.

Would you be able to advise me such type of a good-quality mic, which ideally is connectable to an amp with a (mini-)jacket

Thanks in advance for your answer
