The Levana EQ Booster is a boost pedal from Studio Blue's Levana Audio line, reviewed by Premier Guitar in June 2023. At its essence it is a preamp built into a compact pedal, and what sets it apart from a plain clean boost is frequency selectivity: as Premier Guitar put it, it is "a pedal that can selectively boost a specific band of high-end frequencies to tailor your tone"1. Where a graphic EQ pedal lets you boost or cut gain at fixed frequencies with multiple band sliders2, the EQ Booster focuses its boost on one band of high-end frequencies, lifting the parts of the signal that add clarity and definition rather than raising everything at once.
A boost for a band of high frequencies
Most boost pedals raise the level of the whole signal. The EQ Booster instead targets a specific band of high-end frequencies, which is a different tool: rather than simply getting louder, the idea is to make the most pleasing frequencies in the guitar's signal more present. Premier Guitar's reviewer found the results striking, writing1:
"The pedal’s ability to boost the most pleasing frequencies in the guitar’s signal is utterly astounding and it can give you an otherworldly amount of sustain, clarity and note separation where you need it."1
That combination of boost, clarity and note separation is what a player hears in practice: notes hold longer and sit more distinctly in the mix. Beyond the frequency-selective boost, the pedal carries a conventional control for volume, so it can also serve as a straightforward level boost1.
The enclosure is worth a note. It looks like a wooden casing, but Premier Guitar found it is really a silk-screened piece of sturdy, weighty bent metal1, so the wood appearance is cosmetic rather than structural.
How it compares with other boost/EQ pedals
The boost-plus-EQ idea shows up across several makers, in different forms:
| Pedal | Approach |
|---|---|
| Levana EQ Booster | Selective boost of a band of high-end frequencies, plus volume1 |
| Diamond Pedals Boost / EQ | Boost overdrive with a tilt EQ control and mids sweep3 |
| J. Rockett Hightop Boost/EQ | Boost/EQ collaboration with Mark Sampson, true bypass4 |
| MXR Six Band EQ | Graphic EQ with sliders at fixed frequencies, true bypass5 |
The Diamond Boost/EQ, for example, is closer to a boost overdrive with a tilt EQ and a mids sweep3, and Diamond specifies relay true bypass switching and a 9V to 18V DC power range on its product page6. The MXR Six Band EQ takes the graphic approach: fixed-frequency bands you boost or cut with sliders2. The Levana sits apart from both by concentrating its boost in the high-end band rather than spreading control across the spectrum or tilting the whole tone.
Power and connections
The EQ Booster is powered by a 9V wall wart, and the wall wart is included in the box. Premier Guitar's review is direct about this: "And you'll have to use the included 9V wall wart to power the EQ Booster"1. That is a contrast with some competitors: Diamond's Boost/EQ takes a 9V to 18V DC adaptor that is not supplied6, and KSR's Eros Boost + EQ ships without a power supply as well.
The included 9V wall wart is the stated way to power the pedal1. Players who run compact pedalboards off a single daisy chain or a supply with fixed polarity heads should plan around the included wart rather than assuming a standard center-negative 9V input.
On connections, the pedal works with any instrument that has a ¼" output1, which covers the standard guitar rig: instrument into the pedal, pedal into an amp or the next pedal in the chain.
Acoustic guitar, bass and other instruments
The EQ Booster is not electric-guitar-only. Premier Guitar found it "will actually work well with any instrument with a ¼" output to add clarity to acoustic guitars, basses, vocals, brass"1. For an acoustic player fighting a muddy piezo tone, or a bassist wanting more note definition, a targeted high-end boost is a practical fix, and the review's findings put the pedal in play for those jobs. Players comparing options can also look at the Solar Chug EQ Boost, which press coverage notes also works on bass, or the broader bass pedal and acoustic pedal categories.
What reviewers said
Published coverage of the EQ Booster centers on Premier Guitar's 2023 review, and its verdict is strongly positive on the pedal's core function: the ability to boost the most pleasing frequencies is described as "utterly astounding," with the reviewer citing otherworldly sustain, clarity and note separation as the outcome1. The review also flags the practical points a buyer cares about: the true-bypass circuit, the metal enclosure dressed as wood, the included 9V wall wart, and the $275 street price at the time1.

Questions
Is the Levana EQ Booster true bypass?
Yes. Premier Guitar's review describes the pedal as having a true-bypass circuit, so when it is switched off the signal passes through without the pedal's electronics in the path. The circuit sits in an enclosure that looks like wood but is actually a silk-screened piece of sturdy, weighty bent metal.
Does the Levana EQ Booster work with acoustic guitar and bass?
Yes. Premier Guitar found it works well with any instrument that has a quarter-inch output, and that it adds clarity to acoustic guitars, basses, vocals and brass instruments, not just electric guitar. That makes it an option for acoustic players and bassists looking for more definition, not only electric guitarists.
Does the Levana EQ Booster come with a power supply?
Yes. The pedal ships with a 9V wall wart, and Premier Guitar's review notes you will have to use it, since the included supply is how the EQ Booster is powered. Unlike many compact pedals, there is no indication in the review that it runs on a battery.
Where is the Levana EQ Booster made?
The company hand-builds its pedals in Las Vegas using what Premier Guitar's review calls Israeli technology. Levana itself dates back to a 2008 joint venture with the Las Vegas-based Studio-Blue, after which it began offering musical products including stomp boxes.
