Very nice! I love SGs in that classic trans red finish. I think maybe Gibson delayed shipping out the trans red and black ones due to COVID/supply chain issues - it seems like they announced the colors early in 2021 (meaning they would have started some builds in 2020) but didn't ship them until late summer/early fall. So it might have been hanging around Gibson instead of the dealer even with the late 2020 date in the serial number stamping.
