FREE PAPERCRAFT ARP and MOOG SYNTHS. I took an electronic music synth class back in '75 and learned on the ARP 2600 and Emu synths back at College for the Recording Arts in San Francisco. Never could swing a mega ARP or MOOG, but scored an ARP ODYSSEY (white face) back in '76 and Moog Taurus II in 95 and recently the ARP/MOOG software synths.

Bought this original ARP 1974 model used when I moved to LA (found in an advert in The Recyler) in 1976. Although it could use a tune-up it is still in action.
I actually did get this MOOG for FREE. Found in the trash can at my then rehearsal/studio space and all it really needed was power supply adapter and a din cable to connect pedals.
Plus in case you missed it, back in April '09, the SynthGear site also featured those PLUSH FELT SYNTH PILLOWS. You can BUY THEM at ETSY.
