1/2
Independent shopping perspective
The Korena take
Fieldy signature 5-string with active electronics and a mahogany body. Aimed at players chasing an aggressive, slap-heavy modern metal sound.
Strong match
Who this is for
- Slap and pop players in heavy modern styles
- Downtuned riffing that needs a low B
- Players who already know they want an active bass
Consider the trade-offs
When to look elsewhere
- Beginners — the price and 45mm nut are a lot to start on
- Vintage or passive tone chasers
- Players who dislike changing 9-volt batteries
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
45mm nut width
Wide at the headstock end. String spacing suits slap but demands a longer thumb reach.
Detail 03
Active electronics
Onboard preamp with a battery. Higher output, more cut, and EQ you shape on the bass itself.
Detail 04
Mahogany body
Dense and warm. Adds low-mid weight and sustain, and makes the bass heavier on a strap.
Detail 05
19.5mm to 21.5mm neck depth
Thin front to back. The neck feels fast rather than chunky despite its width.
Detail 06
305mm fingerboard radius
Fairly flat. Comfortable for low action and fast runs, less so for big string bends.
Final check
Know before you order
- 01Needs a 9-volt battery for the preamp; output dies when it drains
- 02Five-string sets cost more and need correct B-string gauge
- 03Wide neck — try one before ordering if you have small hands
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does the K5 need a battery?
Yes. The active preamp runs on a battery. Unplug the cable when you're done or it keeps draining.
02Is this good for slap bass?
That's the design intent. The active preamp and string spacing suit slap and pop playing.
03How wide is the neck compared to a 4-string?
45mm at the nut, noticeably wider than a typical four-string. The neck stays thin front to back, so it isn't as bulky as the width suggests.
04What tuning is the fifth string?
Standard five-string bass tuning puts a low B below the E, giving you five extra semitones down.
