Myytävänä huippulaadukas etuaste / DI-boxi akustisen (ja sähköisenkin) instrumentin mikityksen vahvistamiseen. Tässä valmistajan sivulta:
"The Red-Eye Instrument Preamp offers a simple direct-connect solution for musicians playing instruments with high-impedance piezoelectric pickups. The Red-Eye Preamp works well with instruments having passive or active piezo pickups or those with magnetic pickups such as electric guitars and electric basses.
The Red-Eye Preamp’s impedance-matching field-effect transistor input circuit is designed especially to match and track the impedance of passive piezoelectric pickups. That results in a smooth, natural, balanced, acoustic instrument tone. Low distortion, low noise, and generous headroom mean that clear tone comes through even when an instrument is played percussively and loudly."
