Dimarzio crunchlab vs emg 81. (Passive vs active) ( maple board- c-lab rosewood- emg -81) This video I made after a fb post I saw about the differences both offer. I like both. Keep in mind, im not working with much ie: a pretty shitty cell phone video and nothing is mic'd up. Still, for a metal style the difference is negligible in terms of a metal rhythm comparison. The differences are more on cleans and on amps that are not super compressed.crappy Edited version recorded on a Galaxy s6.
