I always keep a spare high E string just incase i do snap mine. Your strings will rust depending on how damp the room is, how much you play and how sweaty your fingers are. If you wipe the strings after everytime you play it should stop them from rusting so quickly.
My friend use to snap strings every week. It does depend on how your playing and how ruff you are with them. Obviously the thicker your strings are the less likely they are to break !
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.
