2017 saw the likes of Elbow, Noel Gallagher and Placebo lend their signatures to the cause and for 2018 Rega has lined up Ian Anderson of Jethro Tull fame, Jake Bugg, Fatboy Slim, and Rag'n'Bone Man - the official UK ambassador for Record Store Day.
As part of this year's celebrations, Rega has already revealed it will be producing 500 limited edition RSD turntables - the deck is a "unique hybrid" of the company's Award-winning Planar 1 and Planar 2 models.
And now we know that 17 of the 500 will be adorned with an autograph. The only way you can get hold of one is to head to your nearest participating record shop or hi-fi retailer and hope the deck you've bought carries a special scribble.
Record Store Day was formed in 1973 and no fewer than 254 record stores will be taking part in 2018. We've already highlighted 11 of the best RSD releases ahead of time, just to give you an idea of some the vinyl gems on offer.
