Bit of a weird one, this. I think I was given this as "not working" and have never gotten around to trying it. Just plugged it in to the FX loop on my HX Stomp and it does seem to work, albeit I'm not really sure what it should sound like -- the pitch knob was drifting a bit but some switch cleaner seems to have sorted that, although it doesn't seem to turn through its full range (goes from -1800 to +1020 or so). Anyway, if you want some very 80s effects this might work -- I really just want it gone so feel free to make offers on that basis. It retailed at £3-400 in the early 80s according to Home Studio Recording and Electronics & Music Maker magazines, so ~£1200 now!
