CRAFTED IN IWATE
Craft
Feel the texture of iron. Hear the sound open with every touch. KGR HARMONY joins Iwate tradition with electronic circuitry to create pedals that stay close to an artist’s sensibility.

01 — CAST IRON / IWATE
Iron and sound,
Craft
It began with a question: how does an enclosure shape tone? Searching for a new material, Keijiro Fukushima visited Oitomi, a Nambu cast-iron workshop in Iwate, in 2019. The potential of cast iron led to joint development that July.
PROCESS
From Fire to Sound.
Melt the Iron
Prepare the mold while working face to face with molten iron.
Give It Form
Pour molten iron into the mold and form the outline of a musical tool.
Polish and Finish
Polishing and layered finishes bring out the cast surface of each enclosure.
Build the Circuit
Install a circuit that responds to the dynamics and expression of the player.
Play and Listen
Judge response and resonance through real playing, not numbers alone.
02 — THE MAKERS
Fire, iron,
and human hands.
Molten iron is shaped in a mold, followed by polishing, painting, and many more hands-on steps. That accumulated work gives iron its expression.

03 — INSIDE THE IRON
Inside the iron,
a pursuit of sound.
Inside the iron enclosure is a circuit that shapes expression. ARARE uses a three-band EQ to deliver high-resolution overdrive without losing the player’s nuance.
That search extends beyond ARARE to MIZORE distortion, KUROFUNE fuzz, SHIZUKU boost, and many other voices.
