 === PCB Modboards ===
 The "MP Modulation Add-On PCB" is a small upgrade PCB made available by '''''1776 Effects''''' and enables a builder to add a warble effect to a Multiplex Echo Machine PCB. With the addition of one of these PCBs, it is possible to create chorused, phased, or warbled sounds - sounds that emulate what would be created using those old original physical tape echo/delay systems. As it turns out, the aging, wearing, and eventual electronic drift of the components on the original units away from their specifications (or the actual stretching of the magnetic tape they employed), resulted in a "this-unit-needs-service"-type of modulation that in many cases ended up being preferred by musicians and listeners.
 It's possible to hook up an MP Modulation Add-On PCB to either the first, or the second delay. If you're only adding one Mod PCB, '''''1776 Effects''''' recommends installing the warble to the second delay. On the second image of the Multiplex Echo, notice the toggle that gives the user the ability to switch the warble between the first and second echoes.

 * Depth Knob - '''"Depth":''' This control sets the eccentricity of the warble effect.  Turning the knob clockwise will make the warble more extreme; counter-clockwise, less extreme.
