There are two knobs on a guitar. One is the tone knob, which is used when tuning the guitar right pitch and sound you want out of the guitar. The other is for your volume, which is obviously used to toggle between the loudness or quietness of the guitar.
On the head of the guitar there are the tuning knobs. If you tighten them, you get a higher pitch. If you loosen them you get a lower pitch.Hope this helps :D
The ones at end of a guitar (on the headstock) are called tuners, tuning pegs or tuning posts. The ones on the front of the body are the control pots/knobs (volume, tone).
You turn the knobs to change the pitch. I would reccomend buying a guitar tuner that will show if the string is sharp or flat.
Almost any hardware store will sell knobs that can be used as piano knobs.
The toggle switch selects different combinations of the pick-ups.If guitar has 3 pick-ups then you should get 4 variations plus in between settings.Also the treble and tone knobs can be used to good effect.
Try turning down all knobs on your bass. Some basses have two volume knobs, one for each pickup.
Not that my name references the thing your talking about, but a machine head refers to the metal knobs on the stock of the guitar that you twist in order to tune a guitar and that is what the strings are wrapped around. My name refers to the band.
Its where the strings are stretched over from the tuning knobs. Its sometimes called the 'zero' fret.
It is used for focusing.

Either effect pedals, the knobs on the bass itself, of the bass-mid-treble controls on the amplifier
Glass knobs can be used as regular door knobs or as hooks to hang clothes from. Other use might be to decorate a room. For example one can fill a vase with glass knobs and display it on the entrance of a house.
