a detailed process:

play as fish, get to L1 0-1, pick up the guitar(DON'T WORRY ABOUT THE BLACK SWORD FIRST YOU'LL GET IT LATER I'LL EXPLAIN), get to the crown vault, leave, get to the crown vault again, look for the proto chest, put the guitar there and leave it there, get out of the vault, quit, play as the chicken, leave your sword at 1-1, get to L1 1-1, pick up the black sword, get to the crown vault, leave, get to the crown vault again, get the guitar along with the black sword.

Now if you didn't get that, I'm sorry, but that's the best I could do to explain how you're going to get both the black sword and guitar on the same run.
