F#4 Drone Flute ⚫️ 432 Hz (Pre-Release)

F#4 432 — the best-seller, reborn.

This is the key that started I AM Sound.

Our first 4th-octave drone. Designed with Ibrahim in Egypt. Carried forward by Jer. Played, loved, sold out, and asked for ever since.

Now the F#4 432 returns in black as a made-to-order pre-release.

F#4 sits in the center of the stack: present, steady, and easy to reach for again and again. It has the feel of a true flagship — focused enough to lead, open enough to follow wherever the session wants to go.

Start here if you want the classic F# experience: the 4th-octave center, the 432 tuning, the real instrument behind the legend.

DISASSEMBLY / ASSEMBLY:

This drone flute arrives assembled in numbered pieces. To disassemble for portability, gently wiggle each joint apart (don't force it). To reassemble, follow the numbering sequence: press the pieces together part-way by hand, then tap into place on a soft surface (a rubber mallet works great too) until they lock. This keeps the airways tightly sealed for optimal tone.

Play the key that started the voyage.
