yes and yes. they were paid to screw me.
its somewhat in tune but the sound quality still sound bad. i can overlook that but the sharp strings hurt my fingers each time i press against it. if i continue, it will eventually cuts my fingertips.
the strings before this ones that the guy replace for me also sound bad too. i remember my music teacher tune it for me and it still sounds bad. each time my fingers press the strings against the fretting board, it hurts.
the only time that the sound sounds very good was when i first bought the guitar that comes with the strings. even before it got tune up, it still sound very good. after a different music teacher tune it up, its sound even better.
afterward, the 2nd music teacher purposely drop my guitar and it makes the strings sound flabby. he told me to replace the strings. that time i didn't know he purposely drop my guitar. i thought it was an accident. after i paid the store worker to replace the strings for me, the sound quality still suck but at least it doesn't sounds flabby. Not only that but the strings hurt my fingers each time i press against it.
