Born from the legendary front-end of the Ampeg B-15 amplifier—the tube-driven tone that powered classic Motown and rock recordings—the A-Designs REDDI V2 is far more than just a DI box. This dual-mono tube powerhouse delivers warmth, clarity, and unmatched flexibility for bassists, guitarists, synth players, and engineers. Let’s go over why it’s become a studio and stage staple.
The REDDI V2 solves a critical problem for bass players: signal splitting without tone loss. Here’s how pros use it:
Send one channel to a clean amp (e.g., Ampeg SVT) and the other to a gritty tube amp (e.g., Orange AD200). Blend both for a massive tone. “I run one side clean for punch, the other through fuzz—it’s like having two bassists,” says session pro Tony Levin (Peter Gabriel, King Crimson).
Channel 1’s XLR output feeds the front-of-house mixer (pure tube tone), while the Thru sends to your stage amp. No more weak DI signals!
For studio magic, chain the channels: Bass → Channel 1 Input → Channel 1 XLR Out (clean to FOH) → Channel 1 Thru → Channel 2 Input (with effects) → Channel 2 XLR Out (effected to FOH). This creates a wide stereo image—perfect for rock ballads or synth-bass tracks.
With a 20Hz–60kHz range, the REDDI V2 adds tube harmonics to sterile digital synths. “I run my Moog Sub 37 through it—instant ’70s vibe,” says producer Danger Mouse.
The high impedance input preserves the natural resonance of upright basses. Jazz players love its ability to handle piezo pickups without harshness.
While most DIs suck tone from guitars, the REDDI’s 6N1P tubes add richness. Try it:
Engineers at Sunset Sound have used the REDDI as a vocal tube preamp for lo-fi grit. Mic → Preamp → REDDI → DAW.
Set input levels so the tube just kisses the signal (LED flickering at peaks). Too hot, and you’ll lose clarity.
Use high-quality TS cables for inputs and balanced XLRs for outputs to prevent noise.
Whether you’re a bassist needing split-signal flexibility, a producer craving tube warmth on synths, or an engineer tired of lifeless DI tones, the REDDI V2 delivers. As Chris Lord-Alge puts it: “It’s the only DI that makes me smile when I see it on a session.”
