Roland JX-03 Synthesizer Boutique Series

This is the Roland Boutique JX-03.
I am listing it for collection consolidation.


I purchased it used and have not used it since. Basic operations such as power on, sound output, and operation of each button and knob have been confirmed.
*Please understand that not all functions have been confirmed.
If there is an initial defect such as the power not turning on or no sound, please contact us.


- Main unit
- Instruction manual
- Original box
*A power adapter was not originally included. It can be powered by 4 AA batteries or USB Micro-B.

We will pack it carefully and ship it.


This is a compact sound module based on the legendary synthesizer JX-3P released in 1983. It reproduces the original circuit operation with the latest technology while incorporating modern expansion features.

① Integrated PG-200 Controls
It features all 24 knobs from the dedicated programmer PG-200, which was sold separately for the original unit, on the panel, allowing for intuitive sound creation.

② Sound Exceeding the Original: It includes new waveforms (LFO/DCO) not available at the time, an expanded DCO range, and an additional cross-modulation mode.

③ High Portability and Convenience: It is compact, about the size of an A4 file, and supports battery operation, USB bus power, and has a built-in speaker.

④ Expansion Features
It also includes a 16-step sequencer, a ribbon controller for pitch bend and modulation, and the ability to chain two units together to increase polyphony from 4 to 8 voices.

I am also listing many other items.
