I've been using a Digitech RP350 with Richard Hunter's patches to get a Hammond organ effect on some tunes my band plays. Most of these tunes I play diatonic but recently we started playing Booker T's "Time is Tight" (The Blues Brother's Intro Tune) and using this effect on open chords chromatic is just killer.
Check out this YouTube video for a taste.

Of course I forgot to swith to the effect at the start of the song so you can really hear the difference between normal amplification and the chorus/rotary speaker effect.
I hope you enjoy it. We sure love playing the song.
See you at HCH2 in just three days!
