"Refurbished and purchased from Syntaur only a few years ago. All sounds are strong, faders and buttons work properly and the onboard analog spring reverb has a sweet vintage tone which adds to the old hollywood black & white cinematic sound of this synth. There is some natural oscillator aliasing (aka slop or smear) but this is part of the thick chorusing sound. Key bed feels great and the lamp in the power switch is solid."

Roland Juno 60 | Ambient soundscape with Fractal Audio FM3
video upload by MIDERA
"I decided to help a friend and replaced all of his Roland Juno 60 sliders. I figured I’d done a lot of similar work for myself, and I’ve had a lot of people help me out so I wanted to pass it forward. Well, after spending 3 hours replacing the sliders, it was 12:30AM and I turned on the unit to test it out. But it went horribly wrong. Nothing sounded right. Noise was always present, the Attack slider didn’t work, Sub was always on, you get the picture. By this point, I was totally stressed out. I had destroyed a $3000 synth!
I tried going to sleep, but it was around 3AM before I could. I woke up the next day, stressed. I ran downstairs to see if it was just something simple I missed, but nothing seemed wrong. All the pins had continuity to the traces they were going towards.
By 5PM that day, I finally wrote on a facebook group. Someone mentioned something regarding the new sliders from Syntaur. He said they’re chassis legs are too short. Specifically, the Attack slider chassis provides ground to IC5, pin 8. But when I checked, there was continuity from the pad to IC5 pin 8. HOWEVER, the pad was NOT connected to the chassis. I quickly threw the old slider in, and magically… it all worked. I couldn’t believe it. That was about 24 hours of terror as I tried to figure out what went wrong.
However, it is now going strong, perfectly. I’m very thankful to that facebook group!
Fractal Audio FM3 used for delay/reverb/fx."

Additional SYNTH CITY Listings
"1981 Roland TR-808 Rhythm Composer - Serial No. 124650
Here it is! What many would call the most famous drum machine of all time. The TR-808 is well known for being the driving force of the hip hop genre and many other electronic genres. It's wonderful set of analog sounds can be heard on countless records and are as popular in today's contemporary culture as ever.
This unit was just serviced and is in perfect working order. The drums all sound incredible, in particular the snare and clap on this model. Unit has a new start/stop and tap switch along with a replaced sequencer board from Syntaur.
Cosmetically it looks perfectly vintage in our opinion. The only real blemish is the white cap on the snare's 'snappy' knob is missing. Fantastic piece of gear all in all!"

A sneaky cheat brings on a momentary sense of elation - is the end in sight?"
