The EchoPathetic was designed by FSB member Allesz (designer of the Crap-Fi Delay and Dirty Punk Repeater). His previous designs use the PT2399 delay chip, but this one is full analog. There’s an input buffer based around one side of TL072, then the signal goes onto the 3102 and 3205 chips. It’s designed to be a buffered effect with the footswitch just turning on and off the delay section, but I figure more people will want to build it with true bypass. For more info, check out this thread over on FSB.
