1969 / 1970 ARP 2500 Vintage Modular Synthesizer Brochure
via this auction
"Original ARP 2500 Modular Synthesizer Brochure. Nice condition but one piece or writing in cover. Very rare to find now. See my other auctions for more coming this week!"
Note this one is slightly different than the one from 1974 here. This appears to be the first time this particular version has been posted here on MATRIXSYNTH. These posts may not seem that special to some, but these are fascinating bits of synthesizer history that many have never seen before.
