F#4 Drone Expansion Pack 440 Hz - Flute Extension System - Exclusive Mystery MULTI-COLOR

IAMSOUND presents the F#4 Drone Expansion Pack in 440 Hz — Modular Kit System

This modular kit allows you to expand and reconfigure your original F#4 Drone Flute in 440 Hz, unlocking new airflow, feel, and playing possibilities within the F#4 ecosystem.

Important Note: Must have the original / v1 F#4 Drone Flute in 440 Hz to go with this!

This expansion pack is designed to match the original F#4 Drone Flute design, preserving the sound, tuning, and playing experience you already know while adding modular flexibility.

This expansion pack includes three F#4 extension modules (C#4, D4, E4) along with a dedicated organizer / storage stand, making it easy to swap configurations and keep your parts clean and protected between sessions.

Think of this kit as the door unlock to the F#4 modular system—transforming your single flute into a flexible, reconfigurable instrument without changing its tonal character.

⚠️ Compatibility (Please Read)

This expansion pack is designed for the original F#4 Drone Flute in 440 Hz.

This expansion pack is not interchangeable with:

• F#4 Drone Flute v2
• Different tunings (432 Hz)

Each expansion pack is tuned to a specific frequency and built to match a specific flute design. Please choose carefully to ensure proper compatibility.

If you’re looking for easier modular removal and reattachment, we recommend the F#4 Drone Flute 440 Hz v2 and its corresponding expansion packs, which feature an updated connector design.

Disassembly / Assembly Notes

Please disassemble with care if doing so for portability:

Slowly wiggle the joints while pulling — do not force

When reassembling, follow the numbering sequence

We recommend:

Connecting pieces part-way by hand

Using a hard floor surface (with rug or carpet)

Gently tapping pieces into place until they lock
(A rubber mallet works great if needed)

This design ensures the airways remain tightly sealed for optimal sound.
