ER-23 Echo Reverb Master
The Shin-Ei ER-23 Echo Reverb Master is a captivating blast from the past - a vintage Japanese spring reverb unit that transports you to the golden age of analog tone. Designed by the legendary engineer Yellow, this pedal houses a real, physical spring reverb tank, delivering the rich, swirling ambiance that defined classic rock, surf, and psychedelic guitar tones. Unlike typical stompboxes, the ER-23 operates more like a studio effect, with separate gain controls for its three input paths - high and low impedance mics, plus a line/instrument input. This versatility allows you to run vocals, guitars, keyboards, and more through its discrete, vintage-voiced preamps, which can be driven for a touch of pleasing saturation. The single reverb spring provides a lush, enveloping wash, with the "Echo" knob controlling the overall reverb level and blend. And unlike modern digital reverbs, engaging or disengaging the ER-23 introduces a smooth, organic ramp, preserving the natural character of the analog circuit. Whether you're recording in the studio or performing live, the ER-23 is a unique and inspiring tool, capable of adding depth, dimension, and that elusive vintage vibe to your sound. Sought after by discerning guitarists and producers, this rare Japanese gem is a true sonic treasure.
