Your first glance at the Audio-Technica AT831b may make you think that this little cardioid condenser lavalier microphone is only suited for the voice — but, don't let your eyes be the judge. Many musicians and engineers are finding out just how versatile the Audio-Technica AT831b really is. If you have, say, a straight-up acoustic guitar — without electronics — you can easily use the AT831b and an included clip, to achieve a crisp, full-sounding amplified voice. You can also grab other notoriously hard-to-mic instruments and simply clip on the Audio-Technica AT831b.
