Description

The United UT Tube67 is a faithful homage to one of the most legendary studio microphones ever made, renowned for its velvety, full-bodied tone that has shaped countless classic recordings since the 1960s. Designed around a NOS EF86 pentode vacuum tube, a custom United K67 dual-diaphragm capsule, and a US-made UT-BV12 transformer, this microphone delivers the silky-smooth top end and warm, intimate character that engineers and artists prize for vocals and instruments alike.

With its switchable "Air" mod for subtle high-frequency lift, wide polar pattern selection (Cardioid, Omni, and Figure-8), and boutique-level construction, the UT Tube67 excels in capturing everything from vocals and acoustic instruments to full ensembles. Built with uncompromising attention to detail-including a custom Sommer 7-pin cable, regulated power supply, and precision assembly in the USA-the UT Tube67 is a versatile studio workhorse that combines vintage magic with modern reliability. Ideal For: Vocals, acoustic and electric guitar, piano, brass, woodwinds, percussion, room capture, broadcast, and voiceover.
