After my Eventide Harmonizer enthusiasm, I'm getting increasingly obsessed with early digital effects. It's as if you could buy an Apple I, built in Steve Job's garage and use it as your everyday computer instead of a G5. One of the holy grails of old-school digital gear is the AMS RMX16 reverb. It's what Prince used to get the backwards reverb bassline on 'Kiss', and what Phil Collins used on 'In The Air Tonight'. AMS is a company set up by former aerospace technicians in Burnley, Lancashire in 1976, still going today. This RMX16, in perfect condition, just appeared on eBay. A couple of months back, someone tried to sell a non-working RMX16 for $1,487, but didn't get any bids.
Ps: If you're getting into early digital effects, this is the bible: The gear list at Paisley Park Studio B.(Thanks for the tip, Tim)
