What gives the circuit that zzzzzzzz sound?
A resistor, a capacitor and an active device (transistors, 555 timer, etc).
a zzzzzzzz sound is what an oscillator makes. you should learn about oscillators.
Nope! A guitar certainly doesn't have an oscillator.
MStechca, play some music through a pretty good sound system then TURN UP THE VOLUME, WAY TOO MUCH! You'll hear "fuzz" and lots of it if the tweeters survive.
It is called clipping distortion, but old germanium PNP transistors distort differently than modern NPN silicon transistors. Vacuum tubes (valves?) distort differently than transistors.
You should also learn something about the many harmonics caused by amplifier clipping. (Hint, square waves.)
I still have some brand new AC127 and AC128 germanium transistors about 45 years old. Do you want them?
I'm not very far from you so cum-n-get them. :wink:
They are germanium so they have lotsa leakage current and are very sensitive to temperature. They leak current so much that it is difficult to measure their current gain: Nothing in results in lots out. :lol:
