Radial Engineering Headlight ABY Guitar Amp Selector with Drag Control

The Radial Engineering Headlight is a professional-grade ABY and multi-amp selector designed for guitarists who need seamless switching between up to four amplifiers without tone loss or added noise. Built for both stage and studio use, it combines advanced buffering, isolated outputs, and Radial’s proprietary Drag Control technology to maintain a natural playing feel while delivering consistent signal performance across complex amp setups.

At its core, the Headlight features a high-quality Class-A input buffer that preserves clarity and dynamics even over long cable runs. The integrated Drag Control circuit allows you to fine-tune the input load so your pickups respond as if plugged directly into a traditional amplifier, helping retain organic tone and touch sensitivity. Each output is transformer-isolated to eliminate ground loops, hum, and buzz, ensuring clean operation in multi-amp environments.

Designed for flexibility, the Headlight supports ABY-style switching as well as full 1-to-4 amp routing. It also includes a mute function for silent tuning and an “all-on” mode for simultaneous multi-amp output. Bright status LEDs make it easy to see your routing on dark stages, while the rugged steel chassis ensures long-term durability under heavy touring conditions.
