Well, if we assume for the argument's sake that the Leslie is a linear
system the reverb is a linear system (else get a new reverb) and that
neither the speakers nor the amplifier distorts then I claim that for
the mic'd case it won't matter whether the effects are applied pre
Leslie or post mic'ing. Both 'verb and the Leslie can be modelled as
two-dimensional FIR filters and thus where the effects are added in
the chain makes no difference.

But - the Leslie is a non-linear system. Both drivers and amplifier
are non-linear. If the distortion in a particular case was significant
it could change the characteristic of the pre-Leslie-effected case due
to distortion.

IMHO Without hearing them in A/B comparison and just from the above
argument i am sceptical that for normal distortion levels you could
hear a difference.
