ARP Pro DGX 2733

via this auction

"The Pro/DGX is a thirty preset monophonic analog synth with digital controls. The 37-note keybed has aftertouch for volume, brilliance, vibrato, wow, growl, and bend effects - and even all at once if you desire! A few basic filter, envelope and LFO controls allow some tweaking of the preset sounds.

Get your classic Tony Banks sounds with this unique Arp - no other synth sounds quite like it.

This unit has been carefully gone over to ensure that it is fully functional. It has some wear for an instrument of this age, but is in overall excellent condition. Power cord included."
