The M234 Analog Chorus is a modulation effect pedal from MXR that creates lush, liquid textures using bucket-brigade circuitry. The M234 features rate, depth, and level controls to regulate the speed, intensity, and volume level of the effect, as well as knobs for cutting high and low frequencies, which provide greater tone control than a typical chorus pedal allows. It can be used with electric guitar, bass, or keyboards in applications for live performance, recording, and more. The M234 Analog Chorus includes a 1/4" input, a 1/4" mono output, and a 1/4" thru output jack for output to a second amp using optional stereo mode, which creates a wide and sweeping stereo spread. A footswitch toggles the effect on and off with buffered bypass, and an LED that illuminates when the effect is on. Additionally, the M234 pedal comes in a heavy-duty housing, so it is built tough for a lifetime of use on the road. Its small footprint saves pedalboard space, and it can be powered by a single 9V battery or a 9 VDC adapter such as the Dunlop ECB003/ECB003E, or a DC Brick power supply (sold separately).
