We say:

The STC-2 Pack is a great all-rounder for all kinds of voices and acoustic instruments, whether in the studio or in a home environment. It's a favourite with singer/songwriters thanks to its ability to capture vocals and guitar at the same time.

Sontronics say: 

Even though STC-2 is one of our most affordable and accessible microphones, it is crafted with great care and attention to detail, both in its internal electronics and its external build. STC-2’s evenly balanced frequency response results in rich, defined lows and a detailed, open top end, accurately reproducing your source in all its glory.
