Electrons are good. Whether boiled into a vacuum from doped metal cathodes or spilling through an array of PN junctions, manipulation of electrons remains one of the highest technological feats in the human race to exert control over reality. Documented renditions being shuttled along copper wire in the predetermined lay-out of signal path. Analog versus digital is nothing more than nit-pickery over what structure of electron manipulation we opt to execute to attain our intended means. Analog being a theoretically infinite resolution rendition of the actual form of real time information one is rendering, while digital is a single bit [two dimensional] structure relying on a massive sequence of packets rendered and reproduced in a specific order to amount to anything. Digital is simply low voltage analog either full on or off through a chain of time. Transistors scaled down to incredibly minute size compared to what you would find in a distortion pedal or tape recorder, but transistors none the less. Digital's claim to fame is the fact that it typically disregards spurious voltage uprisings and externally sourced tom-foolery, that what comprises noise in the analog system is well under the positive pole of on voltage, so it is ignored and escapes amplification in later stages. Our usual execution of an analog system is simply chaining together a series of special application amplifiers, which will result in spurious atmosphere "noise" being boosted in volume to the point at which it is highly recognizable even to the tin plated dull ears of resource guzzling bipedal skin bags, many of which actually prefer the rounded digital corruption sound of .mp3 to tape hiss. ¹ because some apparatus carries a lot of influence as well.
