Independent shopping perspective
The Korena take
Passive reamp box that sends a recorded DI track back out to an amp or pedals. For engineers re-amping guitar and bass in a studio.
Strong match
Who this is for
- Re-amping a dry DI guitar track through a real amp
- Trying different amps on a take without re-recording the player
- Sending recorded tracks through pedals for effects printing
Consider the trade-offs
When to look elsewhere
- Guitarists who need a DI to record into an interface — this runs the other direction
- Live sound use — this is a studio signal-flow tool
- Anyone needing phantom-power features or active gain
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
+4dB balanced line input, 600 ohms
Expects a line-level output from your interface, not a mic or instrument signal.
Detail 03
Variable instrument-level output, 5k ohms
Output is set to look like a guitar pickup, so amps and pedals see what they expect. The level control sets how hard you drive the front end.
Detail 04
20Hz–20kHz +/- 0.2dB
Flat across the audible range. Tone changes you hear come from the amp, not the box.
Detail 05
THD 0.05% at 20Hz
Distortion sits mostly in the low end, where transformers work hardest. Bass re-amping is where you would notice it, if at all.
Detail 06
3.5 x 2 x 5.5 inches, 1 lb
Small enough to sit on the amp or the console bridge. Nothing to rack.
Final check
Know before you order
- 01No cables included — you need a balanced line cable in and instrument cable out
- 02Feed it from a line-level interface output, not a headphone jack
- 03Ground loops between control room and amp room can still hum; check your grounding
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is re-amping?
You record a clean DI signal from the instrument, then later send that recording back out through an amp or pedals. It lets you change the amp tone after the player has gone home.
02Can I use this as a DI box?
No. It runs the opposite direction — line-level in, instrument-level out. A DI takes instrument level in and sends mic level out.
03Do I need to plug it in?
No. It is fully passive and needs no power or phantom power to operate.
04What do I connect it to?
A balanced line-level output from your audio interface goes in. The instrument-level output goes to your amp input or the front of your pedalboard.
