While most sound designers hate when knobs and switches crackle and create noise, we felt there was potential in these flaws. One can create interesting musical tones or individual works with them. It just depends on your imagination. Get creative and try the 50/60 Hz hum of the transformer, the harsh crackling while turning the big knob, or the popping sound of the power button. By increasing the voltage, you can strengthen the crackling. All sounds are oscillator generated, not sample based. No boring repetition . The BAD CONTACT is not an effects it is a noise generator synthesizer. It doesn’t change the original sound, it just adds a special noise.
