General
The Multiplex Echo Machine is a Tape Echo simulator Pedal. Its basically a dual digital delay with an analog sound. So two delay channels are mixed together (Delay1 and Delay2 knobs)The Pedal features 3 different modes and a speed footswitch (to increase the delay time steadily)
There is also a modulation addon (with an LFO). Ive added this to the Delay circuit.
Theres an additional toggle switch (On-off-on) to switch modulation between Delay1 or Delay2 or turn modulation off. modulation pcb also features the knobs Depth and Speed.
For me the modulation has a reverb / vibrato kinda feel to it.

Where is the dept potentiometer?
ReplyDeleteThe depth is part of the mod pcb which is optional and therefore not part of the schematic. Pls check out the 1776 effects docs
DeleteI can not find the depth potentiometer on the scheme, can u tell me where ?
