Welcome to the All-tube, Analog Sound of REDDIThe A designs REDDI Tube Direct Box is a unique unit. By "unique" we mean the effort placed into the REDDI to produce a sound and character all its own. That effort took A Designs Audio back to a place in time when the Ampeg B15 reigned supreme - making liberal use of tubes and transformers. The A Designs REDDI endeavors to not only rebuild that tone, but also bring that sound to pro audio. Plug a Bass into a REDDI and it's a step back in time. Thick, round, solid sounding Bass notes that sit perfectly in the mix. A Designs REDDI is also great for guitars, synths, and any other electronic instrument that requires a direct box for recording. In fact, some recording engineers have said that REDDI is the "best tube DI ever made."A-Designs Audio REDDI at a Glance:Tube direct boxCustom wound large output transformerToroidal power transformerDual triode 6N1P TubeCombo XLR/1/4 Inch input/output connectorsDrop dead RED metal casingTube Direct BoxThe A-Designs Audio REDDI does not add tremendous amounts of gain as the point of this DI is tone, not huge increases in volume. A tube-based amplifier using the 6N1P output tube feeding an A Designs custom-wound output transformer provides the circuit path for your guitar or bass giving you a sound that you can't get through any other device.
