It's always good to see five items on Ebay, all listed as 'rare'. The RE-201 space echo isn't rare. They sell for £250-£300, but at the moment there are two on Ebay UK, both under £150 - this one has only a day to go. I've wanted one for as long as I can remember, probably because they always seem to pop up in the background wherever there are cool people. The Clash probably used them a lot. And Lee Scratch Perry must have half a dozen. (But remember: They can't make everyone look cool.) They look especially good balanced on top of a guitar amp. It's not really the sound - my PodXT can do that - it's the look of the battered green box and the assumption that it will make brilliant noises. I know if I bought one, I'd use it once, then it would sit under the desk, mocking me for believing an old Japanese box could make me cool like The Clash. Anyway, there's always one thing cooler, and in this case, it's the Korg SE-500 - the tape echo which matches your MS-20 synth and SQ-10 sequencer.
p.s. If you've got a RE-201 that's mocking you, and you enjoy the blog, you could always...
