How to improve your juno 60:
For long the juno 60 was not a really respected synth, wat was a
shame. Now it is seen as a classic. One of the issues with those
first analog/digital hybrid synthesisers is that the leak from
digital to analog. If you turn the volume up, you can hear some
digital noise. With this mod the noise reduces to a more
acceptable level. It' simple, just solder one extra heavy wire
from ground to ground like in the picture. Make the green
isolation dissepear by scretching with a screwdriver or so over
the trace. When you use your juno 60 through a distortion (what
is great) your gonna love this mod.
