Alkuperäinen putkilepa, joka soundaa ihan samoin kuin silloin ennen antaen sen ainoan oikean Doppler-efektin, joka on ainakin puolet urkusoundista.

This Leslie tone cabinet is designed for single-channel organs whose pedal range extends down into the lower frequencies. 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) or Slow (Chorale). This model also features a traditional tube amplifier for the "warm tube" sound.

Leslie 122 A on vanhempiin Hammondeihin A,B,C ja RT malleille tarkoitettu Leslie.
