OPTI-MU PRIME - VARIABLE MU VACUUM TUBE COMPRESSOR

A new breed of compressor, Opti-Mu Prime offers unparalleled natural sounding compression in a unique circuit invented by Mike Congilosi II of Lightning Boy Audio. The type of compression as coined by the man himself, is an optically controlled variable mu compressor or "Opti-Mu." A pair of 12AU7 tubes power this super clean compressor. One tube is responsible for driving the optically controlled vari-mu circuit, which constantly readjusts the bias of the preamp tube, based on how loud the instrument is being played. Louder notes cause the bias of the preamp tube to lower, creating a cleaner and lower volume for those moments. This is the only pedal on earth which uses actual vacuum tubes to achieve the compression effect. There are some vacuum tube powered compressor pedals out there, but they are actually optical compressors, which use vacuum tubes for makeup gain. This is not a vacuum tube powered optical compressor, it is an optically controlled vacuum tube compressor. A bit different than anything else in the world. Mastering Engineers prefer to use vari-mu compressors over all other types of compressors because of their transparent natural sounding compression characteristics. Opti-Mu Prime delivers the same stunning beauty of a serious vari-mu studio compressor in a stomp box format.
