“SEQUENTIAL CIRCUITS PRO ONE ANALOG J-WIRE KEYBOARD / SYNTHESIZER.
SERIAL NUMBER = 6330 Includes Operations Manual and Additional Schematics!
This was the Astonishlngly FAB Keyboard / Synth used by Vince Clarke for Most of the Awesome Sounds heard on the LPs; ‘Upstairs At Eric’s’ & (partially) on ‘You And Me Both’.
Please, keep in mind that although this Keyboard / Synth was one of the COOLEST synths ever created in the history of mankind , Some of the Models did ship from the factory with the following Terrible Faults:
(1) All Pro Ones with Serial Numbers ABOVE # 8500 used the Cheap, Terrible (and Faulty!) MEMBRANE Keyboards.
(2) All Pro Ones with Serial Numbers BELOW # 1500 were the ones with the Power Supply (including Heavy Transformer) Mounted on the Printed Circuit Board!
This particular Pro One does NOT fall into Either of these 2 catagories so, you are getting the Preferred J-WIRE Keyboard as well as the also Much more preferred keyboard that has the Power Suppy (including Heavy Transformer!) Mounted on the Metal Chassis where it is much more Stable and less likely to Crack the PC Board which was a common occurrence with those keyboards w/ Serial #’s under #1500.
Having said that, the reason I am selling my Pro One is that suddenly, inexplicably the keyboard just STOPPED functioning properly! Only a few of the keys (4-5?) now trigger at all. Not sure what led up to this but, I did notice last year that some of the keys were starting to make a ‘crackly’ noise when pressed and were often failing to completely trigger their related notes.
That being said, ALL of the other functions of this Keyboard/Synth operate Correctly. I have tested and re-tested EVERY KNOB, EVERY SLIDER SWITCH, EVERY OTHER FUNCTION of this Fabulous Synth and EVERYTHING ELSE OPERATES CORRECTLY AND VERY WELL Including the SEQUENCER (both A & B Patterns) and BOTH the BEND & MODULATION WHEELS.
All is in Good order EXCEPT for the Keyboard. So, therefore I must sell this Item AS IS Due to a faulty Keyboard. Also, note that as pictured the very highest key has broken off at the fragile little plastic knob where it hooks up underneath to the chassis. I have provided pictures illustrating this and will also provide the complete key and essential little spring so, that you can try and repair it by gluing it back on if you’d like.”
