Radial Engineering ProRMP – Passive Reamp Box for Re-Recording Guitars & Effects

The Radial Engineering ProRMP is a passive reamp device designed to take a recorded line-level track and convert it into a proper guitar-level signal for amplifiers and pedals. This allows producers, engineers, and guitarists to reshape tones long after the performance is captured—experimenting with amps, mic placements, and effects without needing the player present. Built with Radial’s rugged steel housing and custom transformer, the ProRMP ensures clean, noise-free operation for creative studio workflows.

Key Features

• Passive reamp design: Converts line-level recordings back to guitar-level signals for amp and pedal re-recording.
• Custom transformer: Ensures clean signal transfer, proper impedance matching, and reduced hum.
• Adjustable output level: Dial in the exact drive level hitting your amp or pedal chain.
• Ground lift switch: Eliminates hum and buzz caused by ground loops.
• Rugged steel chassis: Radial’s bookend design protects connectors and switches for professional durability.

Customer Benefits

The ProRMP gives creators total freedom to refine guitar tones after recording. No need for endless takes—record once, then experiment endlessly with amps, pedals, and mic setups. It’s also ideal for live players who want to capture a dry track for future reamping or editing.
