This is a used Roland JP-08 sound module.
Part of the Roland Boutique series, the Roland 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.
This JP-08 is in excellent condition.
