It offers highly nuanced and authentic sound reproduction in the studio and even onstage. 5 switchable polar patterns, 3 low-cut settings, and 3 pre-attenuations settings make the LCT 840 a highly versatile tool. 

Honest tube sound

The dual triode 12AX7 tube delivers a warm and comforting sound with smooth high frequencies while still preserving the ability to cut through the mix. Low self-noise and high dynamic range exemplify how the LCT 840 is vintage design brought into the present. 

The future of vintage

"OK, how does it sound? In a word, fantastic. Warmest, smoothest, tube mic I've ever used. I do a lot of vintage type stuff like bluegrass, vintage country etc. The 840 is perfect for vocals for a vintage vocal sound. No hype on the high end. No muddyness on the low end. Just a perfectly balanced albeit warm and somewhat dark sound. Running through a tube/transformer preamp results in vintage sound dripping with warmth and mojo."
