Fantastic Violin Mic
Having used a violin pickup for years (and was never really satisfied), I could hardly believe the sound quality that this mic produced. I was able to walk around the auditorium with more than enough gain and no feedback concerns. It is not cheap but well worth the investment. I would recommend this for all musical styles from classical to rock.
It clips on the instrument easily. A different adapter is required to attache to a wireless system. The wireless system will also require phantom power capibility.
