Bill, we can agree to disagree (in a friendly manner, of course), but I have been playing jazz organ for forty years. I know or knew or played with or opposite most of the jazz organ greats of the 60's, 70's, and 80's, and I stand by what I said. You simply cannot emulate an electric or acoustic bass (which is what arranger bass AND LH bass attempts to do) with pedals. The human foot is just not that agile. And for the record, it's not THAT easy to master, either.

Respectfully,
