A little useful modulation daughterboard for your delay circuits. Created by the one and only Chris Stelloh.
I originally made this for Ben Spinks, who verified it. It’s the
modulation daughterboard for the 1776 Effects Multiplex delay and it
works pretty well with just about any PT2399 delay circuit. I’ve listed
my preferred values as well as the originals from the build document.
You can add a toggle between the mod depth and the delay pot to turn it
off and on, but if you simply max the speed/rate knob, the modulation is
no longer audible and the rate LED is static.
