Sequential Circuits Pro One - used

This SCI Pro One is in great condition. Front is very clean, with minor wear on the sides and some scratches on the bottom. It's fully functional and sounds excellent. All keys trigger properly, pots are clean and switches all working, calibration is good and holds tune. This is the more desirable J-wire keyboard version (serial number is 55xx). Please check out the pictures to make sure you like it. The only thing  worth mentioning is the keys are a bit clacky (but they all work fine). If you want us to rebush the keybed for a small fee send us a message.
