From the post
Original info:
"The Space Spiral is a dark and dreamy modulated delay designed to take you across the highways of fantasy. While the delay may be designed around a “dawn of digital” echo processor, the sound is out of this world, man. If you are a fan of the dreary echoes produced by old oil can delays or the ethereal sound of a well-loved tape delay, the Space Spiral is totally going to tickle your tone bone.
The Space Spiral’s delay time ranges from a tight 30ms to a fast and loose 600ms."
Schematic, pcb and info available on pedalpcb website here.
It should fit in a 125B size enclosure.
