My cat actually got lost when it followed us into the village once and we went back up to try and find her but we couldnt. I was worried that we had lost her. Luckily she appeared back at my house the next day or something like that :D
By virtue of their electrical properties, tubes generate a special waveform when they're saturated, which is why tube engineering has tremendous tonal advantages over solid state or DSP solutions, particularly for crunch and lead sounds. Tubes enter the saturation zone gradually or softly, which lends tube-driven tone its trademark yet totally unique character.
