man..i had a great reply written out explaining why it is a valid style and why it is quieter on high gain metal and all that..and then the board went down...so i guess you will just have to stay unenlightened.
i will just rewite this...alex skolnick,dave mustaine,james hetfield,and kirk hammett...what do they all have in common?they are all acomplished musicians in metal,i have seen all of them in person,and they ALL play those simple little damn three string power chords the same way i do.
you see...unlike some people,i don't just grab something and "take a whack at it" or just "figger it out the best ah can"...i went through all this when i first started playing 14 years ago...when i first started learning those chords it was difficult for me to play them in any fashion(of course...i had just picked the instrument up),so instead of just listening to my cousin(who can't play worth a damn and does it like you think it should be done,because that's the way his acoustic playing mother told him),i watched "cliff em all",went to concerts,talked to good musicians who played what i wanted to play...and i learned.
so buddy...if you want to try and tell me to "review my technique",then you are way off base.i am very serious about everything i do and i spend an awful lot of my free time checking up on my technique and trying not to develop bad habits.
if you want to play whatever it is that you play that way,then go right ahead...but do not tell me how to play my style of metal...because i learned it from watching guys who really know what they are doing...and buddy,you are not one of them in my field of music.
i simply try to pass on the information...and i am not fool enough to try to tell a classical or acoustically trained guitarist how to fingerpick...get it?
