Subject:Re: Leslie Vs Motion Sound


I hven't read the other replies yet, but I had a similar experience.
I bought a Leslie, I think it was a 310 or similar number, produced
by Hammond some years ago. It too had a simulated bass rotor. It was
very compact, very loud, but I was very disappointed with the sound.
It was chalk and cheese compared to my 145, irrespectice of
transistor versus tubes. I got better results using the bass rotor
simulation on the Rotosphere and feeding the treble, using EQ., to
the Leslie. It was an improvement but still some way from my 145.

Whilst I can't comment from personal experience, I have heard others
say they prefer the Leslie sim on the Electro, to the Motion Sound
Pro3T, or RS-147. I believe that too much credit is given to the
treble rotor and not enough to the bass rotor. Although the brain is
more sensitive to moving treble sounds, and deep bass is not
directional to any extent ( hence the use by the likes of Bose of
bass subwoofers and treble satellite speakers ) there is a good
portion of the upper bass ( up to 800hz) from which movement can be
detected, and which provides much of the power and grunt of the
Leslie. If the bass rotor weren't that important it wouldn't have
been set to rotate in the opposite direction to the treble rotor,
because it wouldn't have mattered much either way.

I would guess that the Low Pro would be a major improvement to your
rig.

I think more credit is given to the treble rotor as a rule because on
rock recordings or on stage, it's the treble that cuts through and
the bass kind of gets lost, but then the poorer sound isn't noticed
in the mix. The power of the Leslie is in the two units' movement.
This is clearly demonstrated every time there is a speed change.
