Sequential Circuits Pro One J-wire Edition

via this auction

J-wire has to do with how the keyboard makes contact when triggering notes. There is a metal bar that runs behind the keyboard. When you press a key the back of it tilts up of course. On the back is a wire that makes contact with the metal bar and the note is triggered. I once picked up a "broken" Pro-One for $135, if I remember correctly, because it had a sticky note. I opened it up and saw that the j-wire for one note was bent upwards making perpetual contact with the bar. I bent it back straight and all was good. :)

"Cleaned J-wire, replaced lubed bushings so keybed play as close as you can get to as when it was new.

Classic monophonic cem-3340 oscillator based synth with cem-3320 filter chips.

Compared to alongside another classic monophonic synths such as the roland sh-101 this beast growls and roars like a angry panther compared to the softer kitten i.e 101"
