Roland JD-990 Super JD rack synthesizer module, in excellent condition. I’ve owned this since 2003 and it’s been very lightly used — the display is bright, and overall the unit is extremely well cared for.
What’s Included (full package):
* Roland JD-990
* SR-JV80-04 Vintage Synth expansion card (very rare, highly coveted)
* 2 × M-256E RAM cards (adds more patch memory)
* 3 × ROM cards:
• JD-9D1 (Modern Masters)
• JD-9D2 (Modern Sonics)
• JD-9D3 (Oz Perspective)
* Original manuals (two guides)
* Power cable
If you've ever wanted to own a JD-990, this is the definitive package!
Condition:
* Unit is in great cosmetic shape — no major dings or damage.
* LCD is the original — still bright, no major dimming.
* All functions and expansions work properly.
* Used in my smoke-free / studio environment.
Why this is a rare / powerful bundle:
* JD-990 is already a powerful, 24-voice, multitimbral module.
* The SR-JV80-04 Vintage Synth card significantly enhances its versatility and sound character.
* With 2 RAM and 3 ROM cards, this unit offers much more variety and memory than most JD-990s on the used market.
Selling Because:
I haven’t used it in years, and I’d rather it go to a home where it will be fully appreciated.
Simply put: you won't find a more complete JD-990 package in this condition anywhere else!
