The VT-series microphone preamplifiers will change the way you think of audio quality. The transparency is astounding. Vocals sound smoother, warmer, more intimate, with a compelling presence. Any microphone and any sound will benefit from the improved clarity, definition, and lack of solid-state artifacts.

This VT1 was hand built by Doug Fearn and resided in his own studio rack for many years. I took it as my own studio amp in 2016 

 The VT-1 recreates the sound of classic tube preamps of the 1960s. Modern components and computer-optimized circuitry, unavailable during the vacuum tube era, elevate this design to a new level of performance.

The VT-1 is a single channel pre-amp.
