I've had a buddy's B9 here for a bit and it's a hoot. Once you get the proper technique down there's a lot it can add to an all guitar band in the way of covering certain tunes in a certain way. It may not sound exactly like a Hammond B3 through a Leslie but it's near enough for club work and it helps solve the problem of what does guitarist #2 do to stay out of guitarist #1's way. I'd also agree with those who say that running it through a rotary pedal improves the authenticity of it a bit more. Even a relatively inexpensive one helps.
