Red-Eye TWIN Preamp


Red-Eye Twin Preamp

The Red-Eye Twin Instrument Preamp offers a simple, one-box, direct-connect solution for musicians that play two instruments at the same gig.  It is designed for use with instruments having high-impedance piezoelectric pickups or magnetic pickups.   Performers that would find the Red-Eye Twin useful are, for example, those playing fiddle and mandolin, guitar and mandolin, or string bass and electric bass.

The Red-Eye Twin Preamp’s high input-impedance allows piezoelectric pickups to operate essentially unloaded, which results in a smooth, natural, acoustic instrument tone.  Low distortion, low noise, and generous headroom mean clear tone comes through even when an instrument is played percussively and loudly.


  • Input: high-impedance, 1 million ohms, maximum 1 volt peak-to-peak level.
  • Low-impedance, balanced, XLR output, 600 ohms, will drive long cables to mix-board.
  • A / B Stomp Button selects alternate instrument.
  • Mode Switch allows playing alternate instruments or both instruments
  • Separate Treble controls and Gain controls for each instrument.
  • Boost Stomp Button with Boost Gain control for amplifying solos.
  • Long 9-volt battery life (~100 hours). 
  • Automatically uses XLR Phantom Power, when available, instead of the battery.
  • Plugging an instrument in or connecting XLR phantom power turns Red-Eye on.
  • Automatic power check: Pwr OK Light flashes for 1 second when preamp is powered up.
  • ¼ inch output and input for accessory loop, suitable for stomp-tuners or effects boxes or for output to on-stage guitar amps or PAs.
  • Internal filtering to reject radio-frequency interference from neon lights and cell phones.
  • Small Size: 1.25 x 3.5 x 4.5 inches.  Weight: 18 ounces.
