Not being funny, but surely that means it's in Eb minor lol? I always find it odd when people describe stuff as being in such and such a key when it's, basically, it's not, e.g. when I've come across people doing vids on how to play, say, SBS, they say 'it's in Bm but Edge plays it half a step down' - clearly then, it's not in Bm lol? It's being played where Bm traditionally is on the fret board, granted, but the fact it's half a step down means it's a different key altogether lol.
Just a little bugbear of mine.
Back in the day I used to tune my Les Paul and Strat down half a step, but since I got my Explorer I just leave everything in normal. If I want to play along with backing track that are in alternative tuning, I just edit them to fit normal tuning

That or stick on a capo and work out an alternative way to play a song
