Design studio Case-Real have designed a very pretty amplifier for the Japanese Elekit.
With the vacuum tubes the amp looks kind of retro, but uses modern technologies.

Unlike other kits from EK Japan that have to assembled at home, this one is ready to go.
There’s no information on prices yet, but does it really matter for this piece of art?
