Spring Reverb module for my DIY Modular Synthesiser, after Ray Wilson of Music From Outer Space’s design. Uses a salvaged spring tank.
While visiting my local makerspace and browsing the “junk shelves”, I spotted a spring reverb tank, so I took it home for later use.
Not much later, I found that Ray Wilson of Music From Outer Space developed one more module before he sadly passed away. It happened to be a reverb module for use with a spring tank.
This module is essentially directly that circuit design, with perhaps minor modifications to account for my system’s different power supply.
It offers input level control, and two voltage-controlled amplifiers controlling how much of the original (“dry”) signal, and how much of the “wet” signal makes it to the “mix out”.
- Little bit of circuit design
- Schematic capture (KiCad)
- PCB design (KiCad)
- Panel design (Inkscape)
- Laser cutting at local makerspace
- PCB assembly (through-hole soldering)
- Panel assembly
- Wiring to reverb tank
