That Ventilator pedal had some really nice sounds. The detail in the mids and treble nearly matched the real Leslie, even when piped through a guitar speaker afterwards. The Lex wasn't far off, either, though, and would probably sound better than the Ventilator if running through a FRFR setup. Either would be a good choice for a pedalboard, I think. The Lester had a great-sounding drive in it, that really captured the Jon Lord "driven balls-out" cathode-biased 6550s in heat Leslie sound. If you could get that drive in a pedal, I'd buy it.
