The future of vintage
Innovation and heritage brought together
The LCT 840 is just like its place of origin - Vienna, Austria - a mixture of old and new, traditional heritage and high-tech. We love rich tube sound and we love modern design. Combining them both in the LCT 840 is a dream come true for all recording professionals.
"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."
