I think I'd ask Adam. I see on the interwebs that 3/4's can vary between 22.3 and 24, but if the scale is supposed to be 22.5 that looks a bit too long.
Do you plan to use the trem? If not I can think of one more option ... But I'd still get in contact with Adam.
BTW, have you checked the scale length? If you don't have have a serrated straight edge yet, a guitar repair shop should. It's possible you have a full sized neck.
