Subject:Re: Chorale Effect

Some Leslies (145/147 among others) also had a "brake" plug interface where
none of the motors are energized - the rotors come to a dead stop. Going
from chorale to stop has a very powerful and subtle effect. It's great for
songs which just drop down to nothing, and if you're hanging a ghostlike
chord and the motors stop, the effect just KILLS. I don't have a brake
interface on any of my Leslie, but sometimes I'll just reach back and grab
ahold of the horn rotor to achieve the effect.
