Mosphoros – The MOSFET Bringer, is our pride of an overdrive. Effortless, fluid, unforced gain. From clear lift to full harmonic bloom, it adds weight and width without masking your guitar, keeping your sound intact and turning it up in color and size. Bass and Treble guide the feel as much as the tone, shaping depth and air as they push. Hand-built in Basel, 100% original circuit.
A pedal that doesn’t get in the way of your tone but elevates it, preserving transients, enriching harmonics, and bringing the purest form of your sound to life.
What it does
Dynamic Core Control: Mosphoros responds to touch and pick strength with smooth, unforced gain. It moves naturally from clean lift to rich drive, always keeping the guitar’s voice intact. Every note carries depth and color without compression haze.
Active Tone Sculpting: The Bass and Treble controls shape both gain and feel. Turning them up adds body or presence while pushing the circuit harder, creating a living EQ that breathes with your playing. It can sound warm and rounded or sharp and glassy, always balanced.
Harmonic Expansion: When driven, Mosphoros opens up in layers. Lows stay tight, highs stay smooth, and mids bloom with harmonic detail. It adds width and dimension instead of distortion for its own sake.
Range That Adapts: From subtle preamp boost to full overdrive roar, Mosphoros covers the clean-to-driven spectrum with ease. It stacks gracefully with other pedals, works before or after drives, and fits any amp or pickup setup without losing its character.
Mosphoros was built for players who want honest, organic tone with musical movement. It does not color your sound, it amplifies what is already there, turning playing dynamics into warmth, presence, and harmonic life.

This pedal is a beautiful beast. It’s got great clarity at lower gain and really present dynamics, even as you push it harder. The Bass and Treble shape the sound in a really detailed way and altogether it has that lovely driven, edge of break-up feel without losing detail. There’s warmth, great weight and lovely articulation but it is all so smooth. Love it!
