Sound Pure's Take
Condition: Used, Excellent
A staple on pedalboards for decades, the Boss CH-1 Super Chorus delivers clean, shimmering modulation with exceptional high-frequency clarity and spatial stereo depth. Housed in Boss’s legendary roadworthy enclosure weighing 15 oz, this compact stompbox features stereo A/B outputs for expansive multi-amp rigs. Intuitive controls for Effect Level, EQ, Rate, and Depth allow players to sculpt everything from subtle analog-style warmth to crisp, modern chorus shimmer. Outfitted with reliable buffered bypass switching, a 1MΩ input impedance, and a low 55 mA current draw, it operates via a standard 9V battery or PSA series AC adapter to ensure pristine signal integrity in any performance setup.
From Boss
The CH-1 delivers the genuine tone of the classic BOSS chorus effect—clear, shimmering, and instantly musical. Designed for players who value simplicity, the pedal’s intuitive controls make it easy to dial in everything from subtle motion to intense modulation. Its stereo output separates wet and dry signals, enabling spacious, dimensional stereo effects that set it apart from standard chorus pedals.
