ROLAND SY-184 SYSTEM 100-M 184 KEYBOARD


Very rare System 100-M four voice CV controller keyboard with Jupiter 4 style arpeggiator section for sale in superb condition and in original box. This is a stunning full-featured keyboard for a modular synth system.

Will be fully checked and serviced as necessary before shipping.

In superb cosmetic condition: this keyboard is generally very clean with only minor scuffing and discolouration spots to the face. There are also oxidation spots on the rear of the keyboard, around the jack sockets. This does not affect the operation of the unit. The end cheeks are clean with only minor damage around the edges. See photos for more information on cosmetic condition.

• This is a 100v Japanese model and will run fine on North American mains 115/120v without a transformer (we run all our tests using 120v power); however, a step-down transformer is recommended for extended use.

• A step-down transformer is required in the UK/EU.

• We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made unit if required -  we had a link to these in our eBay store here but eBay removed it. Thanks eBay! So you’ll need to check out our store (it’s the 50va unit you need) or get in touch if you need assistance.


We also stock 6-way US/Japanese extension leads to allow you to use several pieces of gear with your transformer. See or store or get in touch for more info.

We find interesting, rare and classic gear and ensure that our customers receive them in as perfect working order as possible.  First and foremost we ourselves are customers, musicians, engineers and collectors; we love fine, unusual, quirky and well-engineered recording equipment and instruments and that appreciation shines through in everything we do.
