I am a Roland dealer (Classic line and some other products) and have heard
nothing about any recall. Current warranty information is available here:
https://www.roland.com/us/support/service_repair/ You will note that the
Classic Keyboard warranty has not changed.
Parts for the Classic instruments are provided by the Roland national
service center in Ontario, CA. I recently had to get a replacement display
panel for a C330 under warranty (for the first time) and one of the techs
at the service center, Spook (yes...that's his name), was most helpful.
Phone number is (323) 890-3771.
Since most Roland products are small enough to transport or ship, the
service centers are accustomed to customers bringing keyboards, etc. to the
center for repair. I would imagine most (if not all) of the regional
centers have never seen a C330/380 and would be completely unfamiliar with
it. I suggest maintaining a relationship with the dealer and/or a local
organ technician who can get parts from the national service center and
provide field service to maintain your organ.
