To adjust your kazoo’s membranes, start by fully tigthening
the screws, without putting too much pressure on them.
The kazoo is almost mute at this stage. That’s also a good
way to carry your kazoo, without the risk of losing a screw
or membrane.
Now hum in the kazoo, from the wide side near number 2 on the
above image, and slightly loosen each screw, just enough to
get a full sound. The correct setting should be quite obvious,
as soon as the membrane works well that’s it.
On models with several membranes, you can mute all but one during
this adjustement by putting your finger on the screw hole,
to hear only the membrane that you are adjusting.
Do not loosen the screws too much, as this could cause a
membrane to let too much air pass through and weaken the sound.
Screws adjusted. Sound checked, Ready? Go!
