Hey Mark, my Ovation is only a few years old and has a slimline pickup , not like the one in your Ovation.
I did have an american made Ovation Elite in the late eighties but only used it live, not to record.
I can only say that I’ve tried the zoom with 4 guitars, 3 steelstring and one nylon , and they all sound great. Two of them have very basic Fishman sonitone pickups, the Ovation their slimline pickup and the nylonstring has a Shadow pickup system.
Hope this helps.

p.s. I use a thicker pick when I record direct. A 3mm pick instaed of the 2mm pick I use to play acousticly and I pick a bit softer for a mellower sound.
