Picture 1. USSR flangers, sent by bag.
Picture 2. PE-11 PCB. Notice the Roman script printing on the circuit board, the 5DIN sockets, and the flat head screws. Reminds me of Electroharmonix stuff circa 1970.
Picture 3. Close-up of components. Note the Cyrillic on the chips.
Picture 4. Close-up of Soviet-style wiring harness. Done with string. Who needs ribbon cable?
