Independent shopping perspective
The Korena take
Pitch correction and hard-tune in a single stompbox, from gentle tuning fixes to the fully quantized robotic effect. For singers who want that sound live.
Strong match
Who this is for
- Pop and hip-hop vocalists who want the hard-tuned effect on stage
- Singers wanting subtle pitch tightening on tough live nights
- Tracking vocals through a board without opening a DAW plugin
Consider the trade-offs
When to look elsewhere
- Singers who want natural, untouched vocal delivery
- Anyone needing EQ, compression or de-essing — that's not this box
- Players expecting reverb, delay or harmony vocals
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
XLR mic in and XLR out
Drops into the mic line before the board. Works with any mixer or powered speaker without a level converter.
Detail 03
Mic input handles -42 dBu to +1 dBu
Wide enough range to take a quiet dynamic mic or a hot condenser without a separate preamp.
Detail 04
Guitar input at 1 megohm
A passive guitar pickup can run through it without tone loss, useful for singer-guitarists on a tight stage.
Detail 05
Better than 104 dB dynamic range
Loud passages stay clean through the box, so clipping happens at your board, not here.
Detail 06
3.5 x 5.4 inches, 0.92 lb
Pedalboard-sized, so it fits at your feet where you can stomp the effect in mid-song.
Final check
Know before you order
- 01Needs external power — no battery bay to fall back on
- 02Pitch correction tracks best on a clean, isolated vocal; stage bleed can confuse it
- 03Does nothing for tone or compression — pair it with a channel strip if needed
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I get the robot autotune sound live?
Yes. HardTune mode snaps your pitch to the nearest note in the set key, which is the effect people recognize from records.
02Can I use it for gentle pitch fixing instead?
Yes. The correction side nudges pitch without the hard snap, so it stays subtle enough that listeners don't hear the processing.
03Do I have to tell it what key I'm in?
For hard-tune to land on the right notes, yes — set the key and scale before the song. Otherwise it will quantize to the wrong notes.
04Does it compress or EQ my vocal?
No. This box handles pitch only. Tone and dynamics need a separate processor or your mixer's channel strip.
