United Studio Tech Tube67
The UT Tube67 is a United’s faithful homage to one of the most in-demand mic designs of all time. The original classics have shaped the sound of countless classic recordings since their debut 1960; renowned for velvety, creamy, full-bodied tone. The UT Tube67’s smooth top-end make it an outstanding choice for vocals, imparting a warm, intimate quality that only can be delivered by it’s 1960’s NOS EF86 vacuum tube. Linear response across polar patterns ensures versatility, excelling in capturing strings, woodwinds, brass, piano, drums, and both acoustic and electric guitars.
Features
- Silky smooth tube sound
- Custom UT K67 capsule
- Custom United transformer
The UT Tube67’s capsule is a custom-made, historically correct dual backplate/diaphragm capsule; skinned in a laboratory clean-room environment and 24k gold-sputtered on 6 micron Mylar. It has been optimized for the microphone’s operating voltage, and tuned to it’s ancestors’ specification; resulting in a smooth sound without the resonance that is found on most modern reproductions. The difference in comparison to other reproductions is incredible.
