Completes the sound!
Like another reviewer on here, I got the Lester K to complete the sound of the Yamaha YC. I have a primary organ rig (a Crumar Mojo, which to my ears is so close to a real B3 that the difference seems more like the difference one might hear between two real Hammonds rather than the difference between the real thing and a clone - but that's another review). I use that for major gigs. But for gigs with only SOME organ, or limited stage space (or limited compensation), I wanted a truly portable rig. So I got the YC, and linked it with a 61-key MIDI board. The basic drawbar tones are very good, but it absolutely suffers from that "too clean" sound of old Rompler organ patches, and the Leslie sim isn't great. It's not giving you the true DUAL ROTOR simulation with different ramp up/down speeds for the rotor and the horn, and it's not getting any of the cabinet tonal coloring, either. And the fast speed is really nothing to write home about. Lastly, the drive in the YC is NOT good. It just adds fuzzy white noise on top of the sound rather than giving you that warm crunch that's integrated INTO the sound.
Enter the Lester K. It has absolutely transformed the YC. I now feel I could use that portable rig anywhere, even an organ-centric gig, and not feel like I'm missing something. No, it's still not the Mojo, but with great drive, great amp sim and rotational simulation of the Lester, it sounds and feels like I'm playing a truly professional instrument. Before, the YC sounded like an "adequate approximation". Now, it' got some real soul in its tone. This is a fantastic pedal for any clone or keyboard patch that can't quite cut it on it's own.
And as always, Sweetwater was prompt, professional and thorough. These guys really understand how to run a business!
