A-Designs REDDI Mono All-Tube Direct Box with Throughput
Key Features
  • For Guitar, Bass, and Other Instruments
  • Wide Frequency Range: 20 Hz to 60 kHz
  • Inspired by Ampeg B-15 Bass Amp
  • Warm, Transparent, High-Quality Sound
Inspired by the Ampeg B-15 tube bass amp, the REDDI from A-Designs is an all-tube direct box for guitar, bass, and other instruments. The REDDI utilizes a 6N1-P tube-driven amplifier that feeds a hefty custom-wound Cinemag transformer, which imparts a harmonically rich tone. The wide-band frequency range (20 Hz to 60 kHz) prevents in-band phase shifts, resulting in outstanding detail and realism. Another benefit of the wide bandwidth is the prevention of low-frequency phase shift by maintaining a linear response extending below the audible bass range, ensuring a full, natural sound.

A-Designs REDDI Reviews

Sweet cream for bass

By Mark
Rated 5 out of 5
Date: 2017-09-18

This DI gives a sweet, warm tube tone to bass. It is extraordinarily simple in design with only one user control: output level. What is does do is produce a a vintage warmth that is very appealing and at the same time revealing of the instrument and the player. The low frequency limit is 20 Hz, not 60 Hz as mentioned in the specs here at B&H.
