Detail 01
Two inputs and two outputs
Two separate signal paths in one enclosure, so you can run two instruments or split a rig without adding boxes.

Independent shopping perspective
The Korena take
9V boost pedal with two independent inputs and outputs plus a dedicated tuner out. For players pushing an already-driven amp harder without restacking a board.
Strong match
Who this is for
- Pushing a cranked amp into thicker rock or stoner-rock saturation
- Keeping a tuner permanently connected without a separate splitter
- Running two instruments or two signal paths through one box
Consider the trade-offs
When to look elsewhere
- Players wanting distortion on a clean amp — this boosts, not distorts
- Anyone needing only a single simple in/out
- Boards with no spare 9V DC outlet
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
Dedicated tuner out at 100 Ohm
Low-impedance feed to a tuner that stays connected, keeping the tuner out of your main signal chain.
Detail 03
1 mOhm input impedance on both inputs
Passive pickups see a high load, so highs stay intact and the guitar does not sound dulled.
Detail 04
Output 1 at 600 Ohm, output 2 at 100 Ohm
Different drive strengths per output; the 100 Ohm side pushes long cable runs harder without losing top end.
Detail 05
12 mA current draw
Very low. It will sit on a crowded daisy chain or multi-output supply without straining it.
Detail 06
9V DC, tip-ring polarity noted on the jack
Standard pedalboard power, but check polarity before plugging in an unfamiliar adapter.
Final check
Know before you order
- 01No power supply mentioned as included — budget for a 9V DC adapter
- 02Boost pushes what is already there; it will not distort a clean amp on its own
- 034-3/4 inches deep by 3-3/4 inches wide — compact but confirm your board spacing
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this distort my clean amp?
No. A boost raises level and pushes the next stage harder. On a clean amp you mostly get volume; the aggressive character comes from driving an amp already near breakup.
02What is the tuner out for?
It gives your tuner a dedicated 100 Ohm feed so it can stay plugged in permanently instead of sitting in your main chain.
03How much power does it draw?
12 mA at 9V DC. That is low enough for almost any daisy chain or isolated supply.
04Why does it have two inputs?
Two independent input and output pairs let you run two instruments or two separate signal paths through the same pedal.
