A bit late now for those of us who purchased this Crossover harp, mine came in the key of E which I don’t need as much as D which the page clearly stated it was. Refund options were $10 partial refund and keep it or full refund. I chose keep it with partial refund as I don’t have an E but don’t have much need for that key.
I just got mine and it is in the key of D so it sounds like somebody just grabbed one and didn’t look for the letter on the top left of the package. Not surprising since the latest screw up I got was a bathroom mirror instead of a transmission jack.
