RhPf Electronics has introduced the Tri-Hormonic Phalanx, an overdrive which allows you to decide which frequencies stay clean and which ones clip.
Using a MOSFET-based circuit and soft-clipping overdrive, the Tri-Hormonic Phalanx reacts very naturally to pick attack and guitar volume knob changes. Its tone-shaping design splits the signal into lows, mids, and highs, processes each band independently, then blends them back together with dedicated level control. This approach gives players something most drives cannot offer: the ability to assign saturation per frequency while keeping the overall loudness completely consistent.
With the Tri-Hormonic Phalanx you can shape your tone to achieve clean low tones with no mud, creamy, focused mids pushed into breakup, and snappy highs that cut without harshness -- or any other combination you desire.
Features include:
- Triple-band parallel signal paths for lows, mids, and highs
- Independent Gain (cream colored knob) and volume Level controls (black knob) for each band, labeled IGF-1 (Bass), GH (Mid), and ACTH (Treble)
- Soft-clipping MOSFET stages for organic, amp-like harmonic response
- Can be used as full-spectrum clean boost or band-targeted saturation
- Powered by external 9v DC supply, center-negative, no battery compartment
- True bypass on/off switching
- Built in Switzerland
Where traditional drives treat the signal as one block, the Phalanx isolates the fundamental regions of the guitar and lets players shape them independently. This means the lows can stay clean and full, the mids can be pushed into focused breakup, and the highs can be driven into crisp harmonic lift without harshness.
Beyond its technical design, the Phalanx carries a personal tribute to the medical condition acromegaly, quietly raising awareness through the IGF-1 (Bass), GH (Mid), and ACTH (Treble) labels that define its identity.
Tri-Hormonic Phalanx carries a street price of $179 and is available at select retailers and directly from RhPf Electronics.
