“Excellent condition Alpha Juno 1 serviced by me.
In addition to a thorough cleaning (including the keybed), I’ve swapped the stock solder-to-board 3v battery with a battery holder that allows for a user installable CR2032.
I’ve gone ahead and added a new battery for the next owner. All ROM sounds are restored and in memory. User banks are blank.
In addition to the above, and most important, I’ve replaced the backlight which as you can see is bright blue. A quick Google search will reveal the pain of replacing the often failing screens in AJ1s (that’s why so many are sold unserviced).
Finally, I’ve calibrated the unit per the Roland service manual.
The unit sounds fantastic. Very warm. It has that classic BBD chorus. Super light, and portable, too, with 49 keys”
