Independent shopping perspective
The Korena take
Compact analog envelope filter for bass. A single-purpose funk pedal for players who want the classic quacky filter sweep without a large enclosure.
Strong match
Who this is for
- Funk and slap lines that need the filter to open on attack
- Crowded pedalboards where a full-size filter will not fit
- First-time filter buyers testing whether the effect suits them
Consider the trade-offs
When to look elsewhere
- Players wanting octave or synth voices — this only filters
- Anyone needing deep control; the parameter set is minimal
- Subtle tone shaping — the effect is pronounced when on
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
Analog envelope-triggered filter
Sweep depth follows your picking strength. Play softer for a partial sweep, dig in for the full quack.
Detail 03
Nano-format housing
Small footprint means tight jack spacing. Angled or slim patch cables help on a packed board.
Detail 04
Distortion switching option
Adds a gritty edge under the filter, useful for cutting through a loud band rather than clean funk work.
Detail 05
Minimal control set
Fast to set and hard to lose, but you cannot reshape the sweep range the way a multi-knob filter allows.
Final check
Know before you order
- 01No battery slot on nano enclosures — plan for a power supply
- 02Filter response depends on your pickup output; low-output basses sweep less
- 03Compressors placed before it flatten dynamics and reduce the sweep
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does it need a power supply?
Plan on one. Nano-format Electro-Harmonix pedals are built around external power rather than an internal battery compartment. Check the required voltage and polarity against your board supply.
02Will it work on guitar?
It passes guitar signal and will filter it, but the frequency range is tuned for bass. Guitarists often find the sweep sits lower than they want.
03Where does it go in my signal chain?
Early, close to the bass. Envelope filters read your playing dynamics, so put it before compression and heavy dirt for the most responsive sweep.
04Is it true bypass?
Check the specific unit before buying if bypass type matters for your chain. Either way, running it through a buffered board avoids high-end loss over long cable runs.
