Z&H Designs V12 500 Series Preamp

The Z&H Designs V12 500 Series Preamp is a modern interpretation of classic 1970s American microphone preamp design, built around Z&H’s own hand-crafted discrete op-amp and transformer architecture. Designed to deliver fast transients, forward presence, and a dense, punchy midrange, the V12 brings vintage character with modern precision. Its expressive response and controlled power make it an ideal choice for drums, guitars, and rock-oriented recording applications where impact and attitude matter.
