What We Think:

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.

Manufacturer Description:

Designed for players who value simplicity, the pedal’s intuitive controls make it easy to dial in everything from subtle motion to intense modulation.
