Empress Effects Bass ParaEq MKII Pedal

Product Description

Equal, at last.

Finally, a parametric EQ specifically designed for bass players. It lets you shape your tone in a way other pedals just can’t.

The Empress Bass ParaEq is the only parametric EQ pedal on the market built from the ground up for bass. It gives players studio-grade tone shaping in a compact pedal format that is purpose-built for low-end instruments, not just adapted from guitar gear.

Following the success of our Bass Compressor—and after hearing from countless players who were already using the ParaEq MKII Deluxe on bass—we knew it was time to give bassists more than a “good enough” EQ. The Bass ParaEq delivers the same transparent, tone-sweetening power that made the Deluxe a favourite, but with frequency ranges, filters, and features tailored specifically for bass.

With a dynamic low shelf, bass-tuned EQ bands, a Hi-Z input for upright players, and an auto-detecting balanced output, it’s built to give bassists the control they’ve always deserved—on stage, in the studio, everywhere.

Parametric Rules

The parametric EQ bands on the Bass ParaEq are engineered to overlap in key bass frequency ranges, giving you precise control over your tone. With the Bass ParaEq, you can boost 200Hz for thickness while cutting 300Hz to reduce muddiness. Each EQ band’s variable Q filter lets you shape your sound as broadly or surgically as needed.

Sound Great in Any Room

Every room sounds different—some boost certain frequencies, others cause feedback. The Bass ParaEq’s high- and low-pass filters are a great starting point to remove unwanted energy and prevent problem frequencies from ringing out. Once you’ve removed what’s not essential, use a narrow Q on one of the parametric bands to target and tame specific resonances.

And if you need to shape the low end without muddying up your tone, the dynamic low shelf has your back. As you increase boost or cut, the shelf’s break frequency adjusts—giving you broad, musical control when you need it and tighter sculpting when you don’t. It’s like having multiple low shelves in one knob.

Get the Most From Your Signal

The Bass ParaEq works with every kind of bass, including uprights. The piezo pickups in upright basses have a very high impedance, which traditional guitar pedals aren’t designed to handle—leading to low-end loss and a dull, thin tone. That’s why the Bass ParaEq includes a selectable 10MΩ high-impedance input, preserving the full fidelity of your instrument.

Need to send your signal over long cable runs? The Bass ParaEq will automatically detect when a balanced cable is plugged into the output and adapt the signal accordingly—so you don’t lose tone or suffer interference.

Features:

• All-Analog Signal Path – Preserves your instrument’s natural character with rich, organic tone.
• Tailored for Bass – The only parametric EQ pedal built specifi cally for low-end instruments, with frequency ranges and fi lter behaviour engineered just for bass.
• Ultra Transparent, Sweet-Sounding EQ – Shapes your tone without masking the details of your sound.
• Tons of Control – With sweepable frequency, variable Q, and ±15dB of cut and boost across 3 bands.
• Dynamic Low Shelf – A responsive shelf that adjusts its range based on how much you boost or cut.
• 10MΩ Hi-Z Input – Perfect for upright basses and piezo pickups that lose low end with standard inputs.
• Balanced Output – Auto-detecting TRS output for clean signal over long cable runs or straight to DI.
• Ultra Quiet – Low-noise design keeps your signal clean, even when boosting.
• +30dB of Clean Boost – Push your signal hard for solos, make-up gain, or amp-driving punch.
• 27V Internal Headroom – High-voltage operation like studio rack gear—nearly impossible to clip.
• Buffered Bypass – Maintains signal integrity across your pedalboard and cable runs.
• Compact Size – Enclosure measures approx. 2.5” x 4.8” x 2.6” with top jacks to fi t any board.
