United Replay Box – the new benchmark in professional reamping
Whether you’re a professional engineer, producer or sound designer – the Replay Box from United Studio Tech is the ultimate tool for uncompromised reamping. It combines two distinct signal paths, superior signal purity and rugged, tour-ready design in one box.

Clean signal or enhanced color – your choice
Transparent Mode uses a custom-wound 5043 transformer made in the USA. It offers +3 dB of passive gain and maximum signal purity – ideal for mastering-grade applications. Frequency response is 20 Hz–20 kHz with ±0.5 dB tolerance.
Harmonic Mode engages a second transformer designed for subtle harmonic saturation and warmth. It provides +5 dB of passive gain and imparts a thicker, slightly more aggressive tone that works great with DI tracks and guitars.
Applications
The Replay Box is the perfect solution for guitar and bass reamping, synths, DI sources, and creative sound design. Its passive, interference-free operation and robust build make it equally suited to studio or live setups.
