Blue’s new Essential Series advances three of their most popular microphones. The Baby Bottle SL combines vintage-inspired tone with modern versatility. The Bluebird SL is an excellent workhorse mic with a transparent sound. The Spark SL provides incredible flexibility to home and project studios. All three mics feature a highpass filter to minimize mud and rumble and a -20dB pad to tackle loud sources. Each mic also includes a wooden storage box and pop filter.
