I like AC/DC the best from "High voltage" - "For those about to rock" but
what is the Angus sound though, because he's played different SG's from different years, the guitar sound is had changed a lot going from "High Voltage" to the "For those about to rock" era.
In the begining it was a lot fuzzier and in yer face like you were in a small room sat next to his amp, but later the sound was different.
Even if he used the same amps the recording techniques changed, different studios, prodution ideas- they might go for a more dry raw in you face feel, different engineers etc, the processing of the guitar track will be different, differnt E.Q., the eq on the valve compressors, the over all processing for the master, and then the mastering process itself, everything will change the sound, and then its down to what speakers you're listening through.
Whats always there in Angus's sound though are very "loose" harmonics which rattle together as they clash and distort seperatly producing a hard edged fuzziness. He doesn't use any distortion on the amp but over drives it in two ways - he has the amps up loud and he hits the strings HARD. He really digs in with a hard plectrum which makes the strings have a high pitched harmonic squeak to them, both the volume and the hard player cause the amp to overdrive but its the POWER SECTION which really counts, not pre amp overdrive so don't turn up the distortion on the amp, turn it down and turn the amp master volume up, and then wait for the neighbours to call the police.
Angus's left hard has got a MASSIVE fast and wide vibrato which is VERY distictive, this is as important as anything else, and more important than what the pickup is, just like most players you would know Angus straight away what ever pickup he used, or guitar and amp even just by his bent vibrato.
