I think you need to calm down on the irrelevent questions my friend.
Stop worrying about how to make a Netsky bass, and concentrate on making your own bass, Production is all about trial and error, and a lot of time and patience. Any synth with a couple of oscillators can be used to make plucked bell stab sounds. Simple triangle wave with some quick attack, short decay and sustain, with plenty of reverb, some subtle delay and chorus and some slight resonance on the filter and hey presto, plucky bell type sound.
