I've got a problem understanding the pickup ? or the sound ? I don't know I got very confused. I wanted to learn how to make guitar effects although I don't know much about music but I wanted to make. On this website : https://sound-au.com/articles/guitar-voltage.htm Here the Peak voltages of E1 is 100mV and E2 is 300mV, the thing is when there is a chord, I guess it is a E1 and E2 played at the same time so E1 + E2 is 300mV it is the same as single E2 which is also 300mV. That doesn't make any sense to me ... So single string makes E1 sound, and another single string makes E2 sound but playing both strings E1 and E2 makes the same sound as E2 ??????

Second thing is my experimentation. I know about interference and phase shift of the signals. But interference means that the sinewaves must add up to each other right ? Here are the images and the link : https://www.geogebra.org/graphing/merap3ws, so the orange function is the sum of 3 sinewaves (f(x),g(x),h(x)). So f(x) is let's say E1, g(x) is E2 and h(x) is E3 so we have 3 strings (guitar has 6 strings the classic one).

We play all 3 string at the same time so we have 3 sinewaves adding to each other sometimes the sum exceeds value "1" which here it is "3". How does the pickup makes these sound into voltages ? for peak sound "1" it is 0.7V or for peak sound of "3" it is 0.7V ? The maks that pickup can make is 1V but I said 0.7V because it is easier. How does it work ??? What if we have sound that has "20" as a value how does the pickup changes the sound sinewaves into voltage sinewaves ?

Hence I couldn't understand why the output of the guitar is maks 1Vpp or 1V I guess ?

I got so lost because these sums are exceeding this value of "1" and how the pickup "knows" what is the pick of the sound or when he uses maks voltage, when the sound peak is "300","3000" etc ? The sums of the sinus can be alot.

PS. If it's possible to make is simple for goofball like me.
