Product Description
The Replay Box by United is the new gold standard in re-amplification. Built upon the legacy of Chad Kelly’s renowned hand built re-amplification boxes, this cutting edge unit provides unmatched performance with ultra low noise and abundant gain. Whether you are a seasoned engineer or a tone conscious musician, the Replay Box offers a seamless and highly flexible re amping experience.
Featuring two distinct transformers, the Replay Box delivers two unique sonic characteristics: Transparent and Harmonic. The Transparent circuit ensures pristine signal isolation with passive gain, while the Harmonic circuit introduces musical saturation, warmth, and enhanced low mid richness. Designed to eliminate common re amping issues such as noise and inadequate gain, this robust unit ensures superior performance without the need for additional preamps or boost pedals.
Crafted for durability, the Replay Box features a rugged aluminium chassis that withstands studio and live performance demands. With insights from industry professionals over two decades, United has engineered a re-amplification tool that raises the bar for quality and sonic excellence.
Key Features:
- Dual Transformer Circuits:
Choose between Transparent mode for ultra clean signal integrity or Harmonic mode for a fuller, more characterful tone. - Exceptional Gain and Noise Reduction:
Provides ample clean gain while minimising unwanted noise, ensuring a flawless re-amplification experience. - Rugged, Studio Ready Design:
Aluminium chassis with recessed controls and removable feet for maximum durability and flexibility.
Transparent Mode:
Designed for the purest signal path possible, the Transparent circuit utilises a custom wound, US made 5043 step up transformer. This transformer ensures exceptional isolation and noise rejection, making it ideal for professional grade re amping. The passive gain structure provides an additional 3 dB boost above the +4 dB line level input from your DAW, ensuring a clean and powerful output without introducing active circuitry.
Harmonic Mode:
For those seeking warmth and character, the Harmonic circuit engages a specially designed transformer that enhances low mid richness while gently rolling off the highest frequencies. This mode introduces harmonic and phase distortion in the sub bass range, adding a natural analogue feel to your re amped signal. With a steeper gain ratio, Harmonic mode delivers a thicker, more aggressive sound.
Industry Proven Design:
The Replay Box is the culmination of two decades of research, feedback, and refinement from engineers using Chad Kelly’s original hand built re amp boxes. Its superior design ensures consistent, high quality performance in any professional setting. Whether in the studio or on the road, its durable aluminium chassis, recessed controls, and screw mounted removable feet offer reliability and flexibility for all recording environments.
