F#4 Drone v2 Expansion Pack 440 Hz - Flute Extension System - Exclusive Mystery MULTI-COLOR

IAMSOUND presents the F#4 Drone v2 Expansion Pack in 440 Hz — Modular Kit System

This modular kit allows you to expand and reconfigure your existing v2 F#4 Drone Flute in 440 Hz, unlocking new airflow, feel, and playing possibilities within the F#4 ecosystem.

Important Note: Must have a v2 F#4 Drone Flute in 440 Hz to go with this!

MYSTERY COLORS (We are mindful of color choices and aesthetic when color-blocking. We used to call these "happy little accidents", but now they feel more like "happy little upgrades".... You'll notice most of my reels demonstrating our flutes usually show a multi-color, because I LOVE them! The price will remain the same on these because it doesn't cost us any extra)

HAVE FUN with the MYSTERY SURPRISE and remember, these are IN STOCK and ship out within a couple of days!

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 while preserving the sound, tuning, and playability you already love.

⚠️ Compatibility (Please Read)

This expansion pack is designed for the v2 F#4 Drone Flute in 440 Hz.

This F#4 Drone v2 432 Hz Expansion pack is not interchangeable between:

• Original F#4 Drone Flute (v1)
• Different Hz (440)

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

If you have an existing v1 F#4 Drone in 432 Hz, and feel your bottom connecter piece is easy enough to disassemble/reassemble, we have v1 expansion packs available as well.

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:

1. Connecting pieces part-way by hand
2. Using a hard floor surface (with rug or carpet)
3. 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.
