Music Thing Modular
Spring Reverb Module
Eurorack DIY Kit
Instructions
Version 0.9
Bend up the two ground rings so it’ll
be easier to solder wires to them. It’s
vital that the nuts are tight and that
the ground rings do
NOT
touch.
NOTE! If the ground rings touch
then
the module will not work
.
Once the nuts are secure and the
rings are apart they are unlikely to
touch each other again… but you
also have to make sure that they
don’t touch the metal shrouds on the
3.5mm jack sockets,
OR protrude
down to a position where they can
touch the aluminium rail in your
synth case
.

There is significant variation in Eurorack case mounting rails.
Take particular care with rails which don
ʼ
t have a lip which stops
the front panel moving vertically beyond a certain distance.
Even with a lip you may find that one or both nuts on the RCA
jacks can make contact with the Aluminium rail. This won
ʼ
t
damage the module but it will stop the real spring reverb working.
You may want to consider putting thick insulating tape on the
inside edge of the case rail to stop this happening. It won
ʼ
t be
visible once the module is screwed into place.
