The model 122A is specifically designed for older Hammond Organs requiring a separate tone cabinet for sound reproduction, such as the A,B,C and RT models.
It is identical to the Model 122xb, with the exception of having a 6-pin connector, and no ¼" or footswitch jack. Please refer to the Leslie Model 122xb for demonstration.
Designed for single-channel organs whose pedal range extends down to the lower frequencies
Two-speed horn and bass rotor
The sound is "separated" with the highs reproduced by a horn rotor and the lows reproduced by a bass rotor. Both the horn and bass rotors can be operated at two speeds: Fast (tremolo) and Slow (chorale)
