This is a simple FET-based in-line preamplifier with high input impedance, useful for acoustic guitars with piezo pickups but without built-in preamps. It can help keep noise levels low, and prevent loss of low frequencies when plugging into devices with lower input impedance, such as guitar amps and line inputs on mixers.
