I have been able to get an organ sound that I really like, actually better than others I have heard on  youtube (even with dedicated organ simulators).   Sort of like Phantom of the Opera.   Pitchfactor, Modfactor, and Timefactor.  I also use a compressor, reverb pedal, flanger, and a sonic stomp, and overdrive.   I have thought of getting a Janglebox compressor but that would be $200.  I am pretty sure that would improve the sound even more though, and it would have other things I could use if for.  Anyone have any opinions on that?
