I had the first original version but the enclosure was too big and I was looking for a more compact version, the sound is identical, the external switches are very nice , excellent project.
A special thanks to @DGWVI for the transistors problems.
with 2 different spray cans, first give the base black (in my case it's a pearly black with glitter) and then blend the metallic gray and then black again on the sides, it's simpler than it seems.
In the photo it doesn't reflect what it is in real life which is definitely more beautiful.
