thanks dude..
u should use chorus in metal riffs.
not much chorus. juz a bit.
not only chorus..u can use a bit of phaser or flanger too to enhance the tone for ur metal riffs..
take darrell dimebag for example...
he used chorus for his riffs in Cowboys From Hell..
listen to cemetery gates, its obvious there is chorus even for the metallic riffs
in 'domination', there is a chorus too but its not obvious..
man, my ears can tell wat effect those people use..
