Leslie 122 XB alkuperäinen putkilepa, joka soundaa ihan samoin kuin silloin ennen antaen sen ainoan oikean Doppler efektin, joka on ainakin puolet urkusoundista.Sopii mm. XK-3 ja NewB-3 uruille ym. joissa on 11 pinninen liitin.
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.

The Leslie 122XB has an 11-pin connector designed to interface directly with the Hammond XB-series of instruments (XB-2,XB-5,XB-3,...).11 pinninen johto sis. hintaan.
