In GBDGBD the locations on the fretboard are the same as pattern 1 major, A is 2nd fret, E is 9, G is 12, etc. So tons transfers from standard guitar right there. Then the DGB strings are literally the same as regular axe so all of your shapes work there. High E on standard is tuned down basically to an open chord so there's a slight adjustment there but in some ways it's easier to hit pretty sounding notes on the high e than standard.
