Unique Roland SH-3 with EXT INPUT LEVEL Knob in Place of PHONES LEVEL Knob

via this auction

"This unit is much more rare than the SH-3A. This is the SH3, Serial number in the mid #1700's Very few of the SH-3 were made. Notable players were Vangiles and Human League. The photos show some wear on the case itself. Otherwise excellent condition and everything functions correctly. All pots, sliders and buttons, keys work perfectly no scratch static noise when engaged. Best price for a fully functioning SH3 on the Web. I've been able to program 303 to 106 to 808/909 sounds and more."

Update via Rod MacQuarrie: "This is a very rare synth. Instead of a headphone knob upper right, it has an external input level knob with external input jack (stock) in the back. The case is different than any SH-3 or 3a I've ever seen. There are no other photos of this version of the SH-3 on the Internet! Keyboard is different too. There's a narrow wood block right next to keyboard, no gray paint behind the power switch/LED. The circuit boards are original "non-A" boards with copper tracings. The lefthand panel is a gunmetal gray, not black like the standard SH-3 and SH-3a. Another anomaly is one of the pots is actually a 5 step pot, but labeled for 4 envelope settings. Maybe the last setting (unlabeled) is for the external input? And no serial number plate to be found! Could it be a prototype? Or one of the very first versions of the SH-3? Even the service notes don't help, since they reference the latter Rev A circuit boards. This synth is a mystery!"

See previous SH-3 posts for reference.

And: "For comparison, here's the circuit boards from a standard SH-3 (not SH-3a). Note that the board and components are laid out differently."

And: "Circuit boards are rare copper first revision."
