Just finished the Grind Customs FX DeProfundis Delay, after trying it out a little bit, this is by far the best PT2399 delay curcuit ive built, the addition of the tone control for the repeates allows you to get really dark sounding echos, and allows you to increase the feedback amount more with it getting out of control. Im going to build the little daughter board for it to add some modulation to the delay.
