Help with shoot me straight /brothers Osborne

Hey guys ! New here and need help tabbing shoot me straight / bros Osborne for a four string … I’m thinking they are drop D but maybe using stnd tuning with effect … either way I can’t get the tab by ear … any help really appreciated!!

Ultimate Guitar has the guitar tuning as dadgbe so I would bet the bass is in drop D as well

Thank you , I’m looking for the bass tab too

Thank you !
