This version says ADM Prime on the top with silver topped knobs.
I had seen them before (Core and Prime) and asked someone during NAMM and they were going to look into it...and I haven't heard back.
This seller is an Electronics Waste Service and has multiples...so possibly these were early models before the Strata Marketing to be disposed of etc and not intended to be sold to the Public as I see there is an ADM Music company that sells ADM Electronic drums..
Originally I seen them at $2K ea..then down to $1K ea...for either Core or Prime.
The Core Module(s) are worthless without the DB25 Harness...which currently are not offered separately.
No idea until I hear back on them....risky purchase.
Keep in mind...this is
Pure Speculation
NOTE:After placing on my watch list..less than an hour later I received a Discount Offer for $699
