M234 Analog Chorus

A bucket-brigade chip delays a copy of the signal by passing it along a chain of capacitors. Rate and Depth then modulate that delay, which creates the chorus movement.

The Low knob trims bass from the effect, which keeps the chorus from muddying low notes. High cuts treble, from about 660 Hz upwards, for a darker sound. Level sets the overall effect volume.

Two outputs give a stereo option. With a second cable in the Thru jack, the delayed signal goes to the Mono output and a buffered dry copy goes to Thru. Bypass is buffered rather than true bypass.
