Hopefully not continuing to derail, but FWIW, I've got a 330 w/P90s and it does sound substantially different. Acoustically, it's louder and more, well, acoustic sounding, more so than my old Ovation (not quite as loud, but not far off and better sounding). Mine is (I believe) a 2017 Memphis-made with the stock P90s. Take this with a grain of salt, though, because I've also got a 2014 345 that I don't think sounds that close to my Les Paul. Anyway...Part of my experience with the 335 style was it sounded so close to my les paul style guitars (was paul-less at the time, imagine!) that it wasnt worth dealing with the large body for a small tonal change.
Hopefully not a derail, but im hoping a fully hollow p90 or bucker guitar would sound substantially different plugged in to warrant having around.
Now back to our regularly scheduled programming (sorry @Stratman68 - wish you the best in your quest!) Heard great things about Eastman! I don't own one, though, so nothing to add.
