The Tri Hormonic Phalanx splits your signal into three parallel paths for lows, mids and highs. Each path runs through its own MOSFET gain stage and its own level control. You can keep a band clean for clarity, push another into harmonic expansion or stack all three for a full spectrum lift. The idea is simple. You decide where the tone opens up and where it stays transparent.
Placed first in the signal chain, the Phalanx shapes your guitar at the source. Drives, fuzzes and modulations react with more focus, more articulation and more headroom. It can be a clean foundation, a selective frequency drive or a way to control the personality of your sound before it hits the rest of your rig.
The names IGF 1, GH and ACTH reference the hormones involved in acromegaly, which inspired the project. The pedal carries that story quietly in both its circuit and its design. It is a functional tool and a personal one.
What it does
- Parallel Band Architecture: Three independent paths for IGF 1 (Low), GH (Mid) and ACTH (High). Each band has its own gain and its own level. You shape saturation and clarity per frequency rather than treating the entire signal the same way.
- Selective Saturation: Push the mids for definition without losing low end. Add weight in the bass while keeping the highs clean. Build harmonic layers exactly where your tone benefits from it.
- Clean or Driven Foundation: Set all gains low for a wide and transparent clean lift. Increase gain selectively to build a blended structure of clean and driven frequencies before your other pedals react to it.
- MOSFET Response: Each band uses its own MOSFET stage for fast attack, organic compression and a natural transition from clean to driven. Harmonics develop smoothly without smearing across the spectrum.
- Always Stable and Clear: A final summing stage blends the three paths with phase coherence. Even extreme settings stay controlled, tight and free of unwanted buildup.
- Designed to be First in the Chain: Works best directly after the guitar. It refines the dry signal and gives everything that follows a stronger and more defined starting point.
- Gain Before Level: The DRIVE controls sit before the MOSFET stages. Turning them can create small crackles. This is normal and simply reflects changes in how each stage is being hit.
The Tri-Hormonic Phalanx is not just another boost, it is a transformative tool for musicians looking to refine their sound, expand their dynamic range, and push their gear beyond its limits. Whether you’re after a transparent clean lift or a gritty boost to drive your distortion further, this pedal is your secret weapon for unlocking new sonic possibilities.
Let the Tri-Hormonic Phalanx redefine your sound while amplifying a meaningful cause. This pedal is perfect for guitarists seeking both tonal mastery and a powerful message.

Off the charts versatile boost!!! How many boosts have gain controls for each of mids, bass, treble??!! โฆand volume for each!! Crazy!!

First I was bit sceptical, but after few minutes with tri hormonic was kinda blew away! Versatility of this beast is incredible. It really helps to define your core tone with touch of from sky. It is my second unit from Rhpf and definitely not the last. KUDOS!!!
