An August Feature Worth Framing

On August 12th, Pedal Haven published a feature on the Mosferatwo that made us stop mid-solder. The piece not only breaks down the pedal’s design and range, but it also spotlights two of our closest collaborators. Philip Czarnecki and Silvio from Loopy Demos. While giving a nod to the interactive tools we’ve built in the RhPf Nerd Lab.

Why Pedal Haven Matters

Since 2016, Pedal Haven has been a go-to space for discovering original pedals and the people behind them. Taylor is not about hype cycles — he is about substance. Their articles balance accessibility with enough technical depth to keep pedal nerds engaged, and they consistently champion independent builders doing something different.

For a small workshop like ours, being featured there means our work is reaching the kind of audience that cares as much about sound and craft as we do.

What They Wrote

Pedal Haven summed up the Mosferatwo in a way that feels spot-on:

“Its saturated yet articulate tone, dry crunch, and melodic grit have resonated with those chasing anything from jangly garage textures to hypnotic, riff-heavy drive. The pedal now finds itself at home across genres — from vintage blues to modern desert rock and everything in between.”

They broke down the dual-stage Drive, the Focus control that shifts the pedal from bold bloom to tight articulation. And the Heart and Bite EQ boosts that let you shape low and midrange presence with precision.

Friends in the Frame

The feature was illustrated with gorgeous shots by Philip Czarnecki — who’s far more than just the person behind the camera. Philip is a gifted guitarist, composer, and educator whose insight, playing, and artistic eye have shaped how the Mosferatwo is both seen and heard.

Pedal Haven also linked to two very different interactive experiences:

The feature also pointed readers toward two ways to explore the Mosferatwo beyond words and photos. Silvio, the mind behind Loopy Demos, creates in-browser experiences where you can turn virtual knobs and instantly hear how a pedal responds — no cables, no downloads, just pure, hands-on exploration.

And then there’s the RhPf Nerd Lab, our own growing library of interactive frequency response graphs. Here, you can see the Mosferatwo’s tone-shaping DNA in real time: twist a knob, flip a switch, and watch the EQ curves shift before your eyes. It’s a visual deep dive into the circuit’s sonic fingerprint — perfect for anyone who wants to understand not just what they’re hearing, but why it sounds that way.

Together, they give players two unique ways to explore what the Mosferatwo can do — one for the ears, one for the eyes.

Why It Means So Much

We’ve always built pedals with the hope that they’d connect — not just with players, but with people who understand the intention behind them. Pedal Haven didn’t just run specs; they captured the spirit of the Mosferatwo.

For a two-person (and one dog) workshop in Basel, that kind of understanding matters more than any headline.
