ABOUT
EFFECTS / IWATE, JAPAN
Made for
expression.
Care for the sound.
Room for expression.
A sound that makes you reach for your guitar.
A pedal to find your own expression.
OUR PHILOSOPHY
Sound,
unbound.
Where the sound goes
is up to you.
KGR HARMONY designs and builds effects pedals in Iwate, Japan.
Circuits and components. The feel of the enclosure. The response to your playing. Each is carefully brought together in a pedal that becomes part of your time making music.
Beyond someone else’s right answer. Towards the sound you want to make.
TWO SERIES. YOUR EXPRESSION.
Two characters.
Your sound.
