Hands-free Harmonica Microphone

Most players know that cupping a harmonica microphone fattens your acoustic and especially your amplified tone. Unfortunately this is impossible for people whose hands are busy doing something else – like playing guitar, or for people with disabilities that prevent them from cupping a traditional mic. Rackit! cups the mic for you! And the built-in Bulletini® mic has already earned high praise from beginners to pros. You get world class tone, hands-free!
