Pretty good for that little bit of added presence, particularly outdoors, and for busking in noisy areas. But methinks it's chiefly designed for electric guitars so EQing is essential for both mic and instrument. Added to the natural acoustic sound of an instrument it is quite worthy, but on its own it lacks acousticness.

Btw, the handle is easily adapted to a guitar strap to sling it over the shoulder.

Mooh.
