Lightly used. Really great Reverb sounds close to as good as Roland Jazz Chorus 

• BOSS AUDIO CH-1 CHORUS EFFECTS PEDAL: The BOSS CH-1 will add stellar sparkle and deeply dense definition to your axe. Armed with the standard controls: Effect Level, EQ, Rate, and Depth, the CH-1 lets you dial in tones from a subtle thickening to a dizzying wave to a full-on Exorcist twist.
• CLASSIC CHORUS TONES: Use the pedal's four controls — effect level, EQ, rate, and depth — to sculpt the feel and dimension of your sound until it's just right. The BOSS CH-1 can take you everywhere from shimmering clean tones to lush ambiences to boat-rocking, dizzying swirls.
• TWO OUTPUTS: The BOSS CH-1 has two outputs for an incredible stereo chorus effect. This is a great way to give your guitar or keyboard motion, both live onstage and in the studio.
