1983 Crumar DP 80

via this auction

You can find a demo of one here.

Check out the trim pots on the right. Close-up pic below.

"Here we have the incredibly rare, vintage, Crumar DP-80! (famously used on Radiohead's 'Everything In Its Right Place') Really reluctant to sell this but I just don't have space for it. It's in amazing condition especially for it age the only thing that doesn't work is the detune knob which i imagine its a very easy solder fix. The keyboard is pretty heavy so i would prefer collection but I am open to using a courier if organised and paid for by the buyer.
There really isn't a lot of info about this synth online so quite hard to price up fairly so for that reason i've put the price ridiculously high and will choose the best offer made."
