During the 1990s, the station was known as "The Wave" with the call letters WBYA (no relation to the current WBYA 105.5 in Camden, Maine) simulcasting the classical music of WAVX in Thomaston. Later, the station was owned by Moonsong Communications, owners of WVOM where it was an adult album alternative station and simulcast WVOM for a time.
The station would carry the modern rock format until Clear Channel sold their entire Maine group to Blueberry Broadcasting. Because of ownership limits in the Bangor market, WGUY and WFZX were to be sold off, carrying an oldies format from September 2008 to February 2009 before adopting the current K-Love format.
