PCBs and FR4 front panel (only) for a spring reverb driver synth module. This module is in LMNC's Kosmo format (20 cm high) and is 10 cm wide.

The design is based on the (open source) Music Thing Modular Spring module. It provides an interface to a spring reverb tank, an Accutronics "brick" digital reverb circuit, or both. This is a new PCB and front panel layout for Kosmo. Circuit is little changed from the original; the main difference is that the Music Thing expansion module (providing a spring/brick mixer pot, and front panel tank jacks) has been integrated.

The user needs to source parts (including the spring tank) and assemble them. (Photo of my own assembled module for illustrative purposes only.) Easy through-hole construction.
