Highlander External Power Supply / Preamp Box.

Get the absolute best performance out of your Highlander acoustic pickup system. This external power supply provides clean, reliable phantom power directly to your guitar’s internal preamp via a stereo (TRS) cable, eliminating the need for internal 9V batteries.

Key Features

  • Battery-Free Performance: Powers your Highlander pickup externally so you never have to worry about a battery dying mid-gig.
  • Studio-Quality Sound: Delivers consistent, high-headroom voltage for maximum dynamic range and zero distortion.
  • Road-Ready Durability: Built into a rugged, compact metal housing designed to withstand heavy stage use.
  • Simple Setup: Features a standard 1/4" stereo input from your guitar, a mono output to your amplifier or PA, and an LED power indicator.
