Post '94 spec DS-1 on AionFX legacy Comet board, Small Clone on MadBean Touch Stone board. Order switch from PedalPCB
Only mod to the DS-1 is the clipping diodes- I opted for infrared LEDs for more output volume, and slightly more dynamic range.
The Touch Stone is built according to the doc, but the added stomp switch throws an extra 150p in parallel with C15, and a 68k and 10n between pins 2 & 7 of IC1 to increase the modulation width / delay time and introduce some regeneration. This second mode also has it's own speed pot (2MB)
