Grand Maestro Anniversary Founder's Edition | Tribrid UIEM | FATfreq x Effect Audio GMAFE
Grand Maestro Anniversary Founder's Edition (GMAFE)
200 Units Worldwide
The Grand Maestro Anniversary Founder's Edition represents the summit of FATfreq and Effect Audio's shared pursuit of absolute sonic perfection. Co-created by founders Benjamin of FATfreq and Suyang of Effect Audio, this exclusive 200-unit release embodies the combined artistry, engineering vision, and acoustic mastery of both houses.
The GMAFE preserves everything that made the original Grand Maestro Anniversary legendary: eight expertly tuned sound settings, boundless resolution, and an immersive three-dimensional stage. Building upon this foundation, the Founder's Edition introduces a new generation of low-frequency performance through Basscannon V2.0+, a breakthrough isobaric dual dynamic driver system developed specifically for this model. This configuration delivers deeper, faster, and more controlled bass, with a level of physical presence and emotional realism that evokes the sensation of a live performance. Sub-bass textures carry greater authority and precision, while maintaining perfect separation and midrange integrity.
Completing the acoustic system is ASCENDIUM, a flagship grade cable crafted with materials sourced from the most revered Effect Audio creations, including Centurion, Horus, and Beyond Limited Edition. ASCENDIUM is tuned to achieve the ideal fusion of reference accuracy and musical expression. The result is enhanced clarity, richer harmonics, improved spatial structure, and a more cohesive presentation that reveals the full depth and nuance of every recording. With ASCENDIUM, the GMAFE reaches a level of refinement that exceeds traditional flagship standards.
The GMAFE remains fully compatible with FATfreq NOAH tuning modules, allowing listeners to tailor the sound with complete freedom. Each Founder's Edition includes a set of exclusive modules. The SuperStage module is tuned specifically for the GMAFE and ASCENDIUM, expanding the sense of space with lifelike instrument placement and remarkable depth. The new Gold module, developed for the Founder's Edition, delivers a transparent studio-grade signature with firm low-frequency control and exceptional microdetail retrieval, suited for mastering-level monitoring and critical listening.
Every GMAFE is presented in a premium wood exhibition case, designed as both a collector display and an elegant long-term storage solution. The natural grain and solid craftsmanship of the case reflect the exclusivity and artistry that define the Founder's Edition.
The Grand Maestro Anniversary Founder's Edition is not simply an upgrade. It is the ultimate expression of what FATfreq and Effect Audio can achieve together. A statement piece for the collector, a precision instrument for the professional, and an unforgettable experience for the devoted listener.

Technology
Developed by FATfreq in Singapore
Bass Cannon™ v2
(Patent Pending) Using proprietary dynamic woofers, bass chambers and acoustic filter networks, FATfreq was able to design the deepest bass ever recorded of over 20dB, concentrated below 200Hz with zero bleed. Not for the faint hearted.
NOAH Modules
Customizable bass chamber technology that revolutionizes in-ear monitoring. Switch out modules for personalized bass tonality and tuning, while doubling as pressure relief valves to prevent ear pressure build-up. Experience personalized sound and ultimate comfort with Noah Modules. Built with Basscannon™
Linear Impedance
FATfreq uses proprietary circuits to correct the non-linear impedances of multi-driver systems. The different output impedances across all your devices cause frequency response to vary. Having this tech ensures consistency in frequency response for all our IEMs when plugged into any device - Be it your mic-pack, mixer board, phone or dedicated DAP.
Sonar La Trompa™
Inspired by the anatomy of the traditional french horn, FATfreq uses exponential horn curvature for gain control and to improve treble tonality via acoustics. Providing you with Smooth, natural sounding highs, grounded by a nice timbre in the mid and low frequencies.
PhaseAlign
The absence of a DSP in IEMs means that we have to match the phase of multi-way systems via Acoustic delay. Using proprietary structures, we were able to align the low, mid and high frequencies such that they reach your eardrum in a coherent manner. Giving you the sound accuracy and resolution demanded on stage and studio.
