JUP-08TThe legendary JUPITER-8 synth is back as a limited-edition module no bigger than a book. Part of the Roland Boutique series, the JP-08 is all about hands-on control and that iconic JUPITER sound. With an array of 36 knobs and sliders from the original JUPITER-8 front panel, the 4-voice JP-08 is highly programmable and encourages sonic experimentation, especially with the built-in speaker and battery operation. Using Roland’s acclaimed Analog Circuit Behaviour (ACB) technology the JP-08 faithfully reproduces the original JUPITER-8 sounds and adds a few new twists in the form of extra LFOs and expanded VCO range. You can even slide the JP-08 into the optional K-25m keyboard unit for a self-contained, go-anywhere synth experience.
NNOTE: The volume on the JP-08 gets lowers as you use it. I read about it online and it seems that is something that happens with this unit that apparently is an easy fix according to my research, below is an excerpt from Reddit. Also with some tape the volume stays the same, rather than that the unit is like new and was used a couple of times: 

"Got fixed by the technician and it cost me $60 for labor. The volume pot was coming apart. Just tightened up the little brackets that hold it together and that took care of it. It sounds like the type of fix I could do myself, but I wouldn't have known how to diagnose."
