I'll preface this by saying I bought the EH Lester K and it has pretty much satisfied my need for a better rotary speaker effect. However, before I added an external effects box I had a much simpler solution to get a serviceable organ, at least good enough for this weekend warrior. I created a Hex layer with four separate organ tones, detuning some slightly along with some other tweaks, then simply used the chorus effect to add that rotating speaker. It's sort of what I used to do in the old days with my string synth and something guitar players have been doing for years. Pretty neanderthal I guess, but it got me by.
