Leslie simulation is ad difficult task for pedal builders. Although this certainly is a nice Leslie pedal, it is not the sound I was looking for.
Pro's : very nice feature set with sustain, drive, compression, ... . I Iike the fact that it is stereo out ! And it has expression input.
Soundwise it can get really organlike at high speed with much sustain
Con:
The sound is eq'd nice but I miss this doppler effect. Something in the bas or so is not sweeping enough. When I compared to a Mobius, I found this sweeping much more present in the Mobius rotary sound. The Lester ties more to their organlike pedals (c9, B9, Mel9 etc). It sounds flatter then the Mobius that is very mid-focused. I liked the take on univibe with the Good Vibes more then the Lester for a Leslie speaker.
But this is a strict personal approach of how a rotary should sound. Other people would like the Lester very much. It is a good pedal.
