  • Gear Critics Is Alive: Cutaway on Mosphoros

    Thomas

    Cutaway Guitar Magazine has published Fer Gasbuckers’ full review of the Mosphoros in its June 2026 edition! Naturally, we wanted to know what he thought of the pedal. What we did not expect was how much pleasure we would take from simply reading the piece. The review is positive, certainly, but that is not what… Read more

  • Mosphoros Reaches Guitar Publications Around the World

    Thomas

    A Launch That Travelled Further Than Expected When we released Mosphoros, several guitar publications around the world picked up the story. The coverage reached readers in North America, France, Brazil, and far beyond those markets. Premier Guitar, Guitar Bomb, Audiofanzine, Guitarload, and Pedais e Efeitos each approached the pedal differently. Some focused on the circuit,… Read more

  • RhPf x Zimer Blind – When a Pedal Turns Into a Human Connection

    Thomas

    How La Chaîne Guitare led us to discover Zimer Blind Sometimes the most meaningful connections in the guitar world start in the simplest way possible: a pedal in a box travelling from player to player. Thanks to Pierre Journel and La Chaîne Guitare, RhPf Electronics had the opportunity to take part in the Tournée Matos,… Read more

  • “Master of MOSFET”

    Simone

    Guitar Pedal X on the Mosphoros Overdrive Stefan Karlsson from Guitar Pedal X recently published a full article on our pride of an Overdrive, Mosphoros: The MOSFET Bringer! The headline alone made our day. Stefan introduces the piece by calling Thomas “Master of MOSFET”. Then goes on to describe Mosphoros as a super touch-sensitive, dynamic… Read more

  • RhPf Electronics × Manuel Guldimann – Collaboration Story

    Thomas

    A visual storyteller with roots in noise, ink, and late nights. Some collaborations begin with emails and planning. This one began with a record sleeve that stopped us mid-scroll. We first came across Manuel’s work on the cover of Gentle Beast’s Vampire Witch Reptilian Super Soldier from Outer Space. Wild, gritty, emotional, and completely unapologetic.… Read more

  • Behind the Scenes – Mosphoros – Part 4: The Graphic Design

    Manuel

    Finding the Shape of a New Myth When I first heard the name Mosphoros, I immediately understood that the character behind it was not just another mascot. The name plays on “the bringer of MOSFET,” and it carries the weight of a newly invented figure in a fictional mythology. My goal became clear from the… Read more

  • Behind the Scenes – Mosphoros – Part 3: How It Works

    Thomas

    The Architecture of Motion Mosphoros was designed around movement. Instead of a single gain block followed by a tone circuit, it uses several interacting MOSFET stages that build texture, depth, and harmonic weight as you play. Each section responds to the previous one, so the sound never just increases in volume; it grows in character.… Read more

  • Behind the Scenes – Mosphoros – Part 2: The Sound

    Thomas

    Beyond Tubes For decades, the holy grail of guitar tone has been the tube amp. The sag, the bloom, the compression, it’s the sound everyone loves. But tubes are also fragile, inconsistent, and, frankly, obsolete. So the question became: why stop there? Why not capture that same organic feel with modern components, and push it… Read more

  • Behind the Scenes – Mosphoros – Part 1: The Name

    Thomas

    The Birth of a God Mode MOSFET Drive Some pedals begin with a sound. Mosphoros began with a challenge.I wanted to build the ultimate all-MOSFET drive. Not yet another “MOSFET-based” pedal that just borrows the diodes for clipping and calls it a day, but one that truly lives and breathes MOSFET tone from input to… Read more
