Swiss boutique pedal builders RhPf Electronics have announced the release of Regista, a fully analog parametric EQ pedal designed to put absolute midfield control directly onto your pedalboard. Inspired by the legendary mid-frequency sections of the Amek Mozart MZ15-RN recording console designed by Rupert Neve, the Regista compresses the tone-shaping power of an 800-kg, £200,000 studio desk into a pedalboard-friendly enclosure.
For decades, guitarists have chased the perfect tone, unaware that the most crucial decisions are settled in the midrange. Standard amplifiers, guitars, and traditional EQ pedals offer rigid preset curves that make these choices for you. Regista hands that authority back to the player.
Studio-Grade Heritage Re-Engineered
Originally, the Amek Mozart MZ15-RN featured dual parametric mid sections quietly obsessed over by top-tier audio engineers. It shaped the sonic landscapes of era-defining records like Nine Inch Nails’ The Downward Spiral and the self-titled Buena Vista Social Club.
Mid-frequency
RhPf Electronics has masterfully captured those two legendary mid-frequency sections, merged them into a single continuous system, expanded the original sweep ranges, and housed it all in an elegant, stomp-fitted layout.
“The Regista is one of those pedals that once you kick it on, you don’t want to kick it off. It behaves like a high-end studio console, giving you clarity, musicality, and a distinct magic that never sounds bad—even at extreme settings.”
— Philip Czarnecki, Gear Demonstrator
Regista Video Demo
To hear the Regista in action—ranging from warm, silk-like tone enhancement to highly focused mid-boosts and studio-style frequency cutting—watch the full video demonstration below:
Uncompromising Analog Architecture & Layout
Where typical EQ pedals lock down specific parameters, the Regista features three entirely independent, continuous controls allowing for absolute sonic precision:
-
Zone: Sweeps continuously across a massive six-octave range from 100 Hz to 10 kHz.
-
Shape: Dictates the bandwidth (Q value). Set it wide for smooth, musical, console-like integration, or narrow it down for a razor-focused, surgical spike.
-
Drive: Delivers up to ±18 dB of pristine boost or cut at your selected frequency.
-
Level: A post-EQ recovery control supplying up to +18 dB of clean output gain.
Running on standard 9V to 18V DC power (fully analog), the pedal includes True Bypass switching and sleek top-mounted jacks to save crucial pedalboard real estate.
Whether placed before a drive to push an amp into harmonic saturation, post-fuzz to cut through a dense mix like a mixing engineer, or paired with bass and synthesizers, Regista acts as the ultimate tone-shaping Swiss Army knife.
FAQ (Frequently Asked Questions)
What makes the Regista different from a standard graphic EQ pedal?
Unlike graphic EQs with fixed-frequency sliders, the Regista is a fully parametric EQ. It gives you continuous control over the exact frequency you target (Zone), how wide or narrow that frequency band is (Shape), and whether you want to boost or cut it (Drive).
How does the power supply affect the headroom?
While the Regista can run on standard 9V DC, it can safely be run up to 18V DC. Powering the pedal at 18V increases internal headroom, making it ideal for high-output instruments, active pickups, and placement late in your signal chain.
Where should I place the Regista in my signal chain?
Placing the Regista before your overdrive or fuzz pedals allows you to push specific frequencies into saturation, altering the texture of your gain. Placing it after your dirt pedals allows you to shape the overall output EQ—acting like a mixing console to clean up muddy frequencies or add a solo volume boost.
Can this pedal be used on instruments other than electric guitar?
Yes. With a frequency range spanning 100 Hz to 10 kHz, it is fully compatible and highly effective with acoustic guitars, bass guitars, synthesizers, and studio inserts.
Verdict & Score
The Verdict
The RhPf Electronics Regista is an absolute triumph in analog tone shaping. Rather than introducing cold, clinical EQ, it breathes studio-grade warmth and musicality into your signal chain. Borrowing DNA from Rupert Neve’s Mozart console, it manages to make even extreme cuts and boosts sound exceptionally natural.
A great tool if you need a subtle, “always-on” sweetening tool or a powerful utility to carve your pocket in a live band mix, the Regista is a premium, beautifully constructed solution that feels incredibly dynamic under the fingers.
