Welcome, Roger. Judging from the time line, you and I are about the same age.
Leslie simulators are now much better. I still use a 145 and a 147 RV on one house job at a country club (we have jazz night twice a month).
Another way I get that Rotating sound "fix" is to use a little Motion Sound "top box". It's just the rotating horns-made by Motion sound. Mine's old, but I saw the new version of the Motion Sound at Summer NAMM last year. Pretty Cool!~
I lived in Oscoda and Tawas City (SP) as a kid...dad was in the Air Force there.
Glad to see you here!
