well i have a rg20th and last year i cleanned it up and remove all of the pups and of course the pickguar, i draw the RG20th's pickguard and also i have a GRG370 which is a Gio but it doesnt uses a pickguard but i want to put one... anyways the rg20th pickguard doesnt fit on the GRG... the GRG is smaller by mm, but i'm guessing that if you want a
custom pickguard on you Gio you should make one...
