How does a talk box work and what does it do?

The talk box uses your mouth as an additional sound chamber, allowing you to form your sound into Words and phrases. To understand the concept, first think about how your form Words. The air is pushed from your lungs, through your vocal chords and then you form the air in your mouth and nasal cavity to produce a different sound. The Talkbox replaces that air from your lungs with the sound of your instrument, allowing you to form it into Words and phrases. The Talkbox takes the signal from your Amplifier Speaker Output and sends it though the hose. You place the hose in the corner of your mouth between your back teeth. Basically, you are replacing the air that is pushed from your lungs with the sound coming out of your amp. You put the hose between your back teeth, because you want that sound starting as far back in your mouth as possible, so that it can be completely formed by your mouth. With the hose in place, play a note with your instrument and form the sound with your mouth. Do not make any sound with your voice, just mouth the sound or Word. Begin by mouthing the vowels, A, E, I, O, U. You will find that the more exaggerated you form your mouth, the better the effect will sound. Next, work on saying Words with hard consonants, such as B, D, G, J, K, P, Q, T, V - "good" "bad" "give" "take" Then move on to phrases and complete sentences. "Bad, Bad, Leroy Brown" You will also find that when you bite down partially on the hose, the sound will change. If you bite down on the hose completely, there will be no sound.
