what is the mesorah for the artscoll ashkenaz siddur? Is this the same nusach ashkenaz that was used in previous generations?
Nusach ashkenaz in artscroll is slightly misleading. 'Nusach ashkenaz' implies the german nusach when really it's minhag polin/lita. So the ashkenaz of artscroll is according to the litvish custom. If you find a siddur that's published in germany or hungary and says "nusach ashkenaz" it will be slightly different
