EarthQuaker Devices Scrolls Bass Odyssey: The Ultimate All-Analog Command Center for Filthy Low-End

EarthQuaker Devices has officially broken the silence on their latest tonal behemoth: Scrolls, a comprehensive bass preamp and overdrive pedal designed to be the “all-analog command center” for the modern bassist.

Developed in close collaboration with legendary Japanese bassist Kentaro Nakao, the Scrolls Bass Odyssey isn’t just another dirt box; it’s a sophisticated tone-shaping platform engineered to bridge the gap between vintage tube warmth and the surgical precision required for modern “ampless” stages and studio sessions.

A New Approach to Saturation

At its core, Scrolls features a tube-amp-inspired overdrive circuit. While many pedals lose low-end definition when the gain is cranked, Scrolls utilizes an onboard Blend knob, allowing players to weave their clean, punchy signal back into the distorted path.

However, the real innovation lies in the Bandwidth control. Moving away from traditional “Tone” knobs that simply cut treble, the Bandwidth dial shifts the frequency where the clipping actually occurs. Turning it counterclockwise yields a thick, “woolly” saturation perfect for stoner rock and vintage soul. Turning it clockwise tightens the response, delivering the sharp, percussive “clank” favored in modern metal and prog.

Surgical EQ and Massive Versatility

The EQ section is where Scrolls truly distances itself from the competition. While it features the standard Bass, Middle, and Treble knobs (with center-detented “flat” positions), it introduces a Variable Frequency control.

This sweepable pot covers an immense range from 20Hz to 10kHz, allowing bassists to target specific problem frequencies. Whether you need to cut “mud” at 250Hz or boost “bite” at 3kHz, the Scrolls offers a level of precision usually reserved for high-end rack gear.

To further customize the response, EarthQuaker has included three voicing switches:

• Deep: An 80Hz boost for earth-shaking sub-frequencies.

• Process: A pre-set low-mid scoop for aggressive, modern “hi-fi” tones.

• Bright: A 5kHz lift to enhance pick attack and string definition.

Pro-Grade Routing and Connectivity

EarthQuaker Devices clearly built this pedal for the touring professional. The integrated effects loop is strategically placed between the drive and EQ sections. This allows you to place your chorus, delay, or reverb after the distortion but before the final EQ shaping, ensuring a cohesive sound.

For the studio and stage, the pedal includes:

• Balanced XLR Out: Featuring analog speaker-style filtering to emulate a real bass cabinet.

• Buffered Parallel Out: To send a dry signal to a tuner or a second amplifier.

• Ground Lift: To eliminate hum in unpredictable live venues.

Hand-built in Akron, Ohio, the Scrolls Bass Odyssey carries an MSRP of $349.

FAQ: Everything You Need to Know About the EQD Scrolls

Is the Scrolls a digital or analog pedal?

It is 100% all-analog, providing a warm, organic response that mimics the feel of a real tube amplifier.

Can I use this as my entire rig for live shows?

Yes. With the balanced XLR output and built-in speaker simulation, you can run the Scrolls directly into the PA system (Front of House) without needing a traditional amplifier.

What makes the “Bandwidth” knob different from a “Tone” knob?

A tone knob usually just filters high frequencies. The Bandwidth knob changes the character of the distortion itself, deciding which frequencies get “clipped” the most.

Who is Kentaro Nakao?

Kentaro Nakao is a highly influential Japanese bassist, best known for his work with the band Number Girl. His aggressive yet articulate tone was a primary inspiration for the Scrolls’ design.

The Verdict: Is the Scrolls Worth It?

The EarthQuaker Devices Scrolls Bass Odyssey is a premium tool for players who are tired of carrying multiple pedals to achieve a single “pro” sound. It excels as a “set and forget” preamp, but its sweepable EQ makes it a tinkerer’s dream.

While the $349 price tag puts it in the boutique category, the inclusion of a high-quality DI, an effects loop, and a studio-grade EQ effectively replaces three other pedals on your board. If you demand total control over your low-end “filth,” this is the new gold standard.

Pros:

• Incredible EQ precision with the Variable Frequency knob.

• The Bandwidth control offers unique distortion textures.

• Pro-level I/O including XLR DI and an effects loop.

• Rugged, boutique build quality.

Cons:

• Premium price point may be high for casual players.

• Large footprint requires significant pedalboard real estate.

Final Score: 8.4 / 10
