Is that the same as the EL that was used in the 1980's on lots of old stereo gear ? Ie.. you'd hit rewind and some little backlit glass-and-silkscreen template would say "Rewind" in blue or green or etc.. I LOVE the way that looks. That's one of the reasons why I love the Amiga CD32 (not that I own one.... yet). It looks like a hifi stereo component from the 1980s. I have a Kenwood electronic EQ and spectrum analyzer that has all kinds of EL elements on the front of it. I still use it daily. It's awesome. -Swift
