Single rotor, Nathan, doing exactly what it's meant to do! I'm racking my brains to think of any theatre style organ rotary cabinet that had horn rotors, except for the leslie 251. The Conns, Baldwins, Rodgers and Gulbransens all managed without.
I liked twin cabs on Conns, one with single rotor and a 251 as well. Mike them right or posistion them 'just so' and the sound could be awesome, especially if you left the internal speakers on as well. Multiple rotors gave the impression of having more than one rank of Tibias, all on separate trems.

It's not what you play, it's not how you play. It's the fact that you're playing that counts.
