Pyramind mentor Jor van der Poel answers the common question: What is a comb filter, anyway? He explains that comb filters are actually not filters at all, but delays. The feedback from the short delay creates a tone in a sound that might not have a recognizable tone. He starts the tutorial applying short delay to a kick drum to show us how this works. This is a must-watch for those of you looking for creative ways to use comb filters.
