I have a 2022 olympic white CV PBass with a CMHC serial number. What's interesting is that the inspection tag that came with it is the same type that Grand Reward used except it has MH on the border instead of GR.
Also, check post #17 on this thread https://www.talkbass.com/threads/squier-classic-vibe-series-qc.1549061/
This one has a CMHC serial number and the inspection tag has the GR on the border which would indicate that it was made at Grand Reward.
Maybe it's the same factory and they just had a name change?
Amazing information! i've always suspected it was the same factory because of the finish of the instruments with CMHC serial number.
In the end, I only kept the neck, and while the trustrod is 4mm Allen Wrench, the quality of the gloss poly finish and binding are very "Grand Reward"y.
