Ideal Tone Every Time
The CH-1 is filled with clear, transparent chorus tones that shine with any musical style. From adding delicate shimmer to arpeggios to enhancing high-gain solos with depth and dimension, this pedal puts it all at your fingertips. The ultra-simple interface is designed for consistency and ease, ensuring that your ideal sound is just a knob twist away.
Intuitive Control
The CH-1 provides modulation speed and depth controls, plus a level control for mixing the chorus effect with the dry signal. The EQ knob functions as a low-pass filter for the effect sound, offering an array of tonal colors with one simple control. Lower settings induce richness and warmth, while higher settings introduce more sparkle and brightness to the tone.
Deep Stereo Dimension
The Roland JC-120 Jazz Chorus amplifier is renowned for its lush, room-filling sound, produced with a stereo circuit and the unique Dimensional Space Chorus effect. The CH-1 features a stereo output inspired by this iconic amp that provides discrete wet and dry signals. When sent to two amps, these independent voices magically merge in the sound field, authentically recreating the wide, immersive experience of the JC-120.
