This fuzz effect for guitars was found in an American 1980s documentation. The transistors may be the BC549 and should be battery powered for noise sensitivity. Diodes are commonly used.
In the figure we present a touch sensor that operates by detecting the 60 Hz snore of the power...
This circuit takes advantage of the noise generated at the reverse biased junction of a germanium...
This crystal-controlled oscillator can generate signals as high as 200 MHz. The L1 coil is made up...
