False redirect from Harmonizer
A Harmonizer is a 19" rack mounted effects unit manufactured by Eventide of New York USA since the 1970's. The Harmonizer H949 includes two digital delays and an Anti-Feedback system which was often used in concert live sound setups during the 80's. Some features of the Harmonizer model H949 exist today as a Plug-In for digital recording.
