Hi Bill

Yes, if you just listen to the Leslie (The only way to hear a B3) then the A100 sounds exactly the same for the reasons you mentioned, however if you use the on-board speakers of the A100 (Either with or without an external Leslie) then the sound becomes smother and loses the bite of a B3 with just the Leslie.

This is the reason I made the comment about the Key B (Numa) being like an A100 when used on its own. (As most purchases will use it)

Happy Playing

Bill
