The TRINITY FLUID CHORUS is based on the circuit of the early Arion Chorus SCH-1, and utilizes Arion Chorus' experience in modifying the circuit, resulting in a clear, crisp sound without excessive bass emphasis. The SCH-Z also had a volume difference where the effect was turned on and the volume was louder than the bypassed sound, but the TRINITY FLUID CHORUS is equipped with a VOLUME control, so you can adjust it as you like. While retaining the great qualities of the Arion Chorus, we've incorporated the opinions of professional musicians to refine both functionality and sound, resulting in a clear and unique modulation. And the unique, fantastical fluid art paintwork that links with the sound has created an artistic analog chorus pedal that will enrich the player's creativity. *Please note that each unit is hand painted, so there may be variations in color, pattern, and unevenness in the paint.
