Jim, my 122 just has an original Jenson driver in it. Sounds very nice and smooth to my ear, but live...just seems like you've got to cut through without sounding screechy. I'd rather be a bit on the dull side as opposed to screechy. Especially since I play with the slow motor unplugged. Seems that in itself can really cause too much treble. But in the end, sometimes it sound good, sometimes not. Even in the same spot in the same club week after week. Plus, I always get the feeling the people out front aren't getting a good sound through the PA. The organ can sound so rich, but at the hand of these terrible soundman...uggg. I get a lot of..."Couldn't hear the bass." Which is a drag, since as you know, a hell of a lot of your attention is happening on the bass-side of things.
