To echo R' Zalman and add, I have [a copy of] the Toldos' son's siddur,
written during the Besht's lifetime, and the Sidur R Shabsai [shliach
tsibbur of the Baal Shem]: they both are nusach Ashkenaz except where
the Ari specified otherwise: e.g. boruch she'omar after hodu, kesser in
kedushas musaf etc

What the Maggid did institute was the use of 'ksav Ari' for all stam.
