via the seller/listing: "This Jupiter 8 was used by Huey Lewis and the news on their hits in the 80s. It has been in my studio for 15 years. I had it thoroughly gone through by the bay area synth guru at East Bay Audio Repair. It had a funky pot that controlled the speed of the arpeggator and a cracked key. Both were replaced. The battery for the memory has plenty of life left in it. It is all in great working condition. It has a JL Copper mod that I believe is a memory expansion. It has a few minor scratches but cosmetically is still in great shape and it sounds FANTASTIC."
