This JEN SX-1000 belongs to Stéphane in France, who wrote to tell me of the three mods he did. I have never seen two of them before – a Tremolo control, and variable filter tracking. Which would make Gordon Reid very, very happy.
So here is Stéphane’s letter:
„Hello, here are some modifications for the Jen synthetone SX1000. Nothing is disconnected. Components are added.“
