I do not mean to veer off the subject of this thread which is specific to Slingerland too much. As far as I can tell, with Roland acquiring DW, Gretsch, and Slingerland, the fate of both Gretsch and Slingerland are unknown at this point.
If you see Rogers drums, are you seeing the used models or the new models? I do not know how any company these days can attract a large following in a new generation of drummers who can not spend much without having an "economy class" drum set. It looks to me that the new Rogers drums is not playing in that segment of the market and they are going for the "mid range" and "high end".
Roland and DW don’t own Gretsch . Fred Gretsch owns Gretsch and DW/Roland own the license to manufacture and distribute Gretsch drums . A brilliant business move by Fred . His former staff still make all the drums but all the headaches of selling and distributing the drums goes to DW/Roland . Fred can back out of this agreement whenever he wants to .
Another company has the license to make the offshore Gretsch drums (Renown, Catalina) and ai cannot recall who it is .
