Tone knob: Alters the distorted portion of the sound. This has no effect on the dry signal
portion. This allows for very warm overdriven sounds that won’t become scratchy if
you try to get more treble out of the instrument.
Drive knob: Sets the amount of overdrive distortion. The output level is automatically
compensated for, so there’s no need for another master volume control adjustment
facility. A level of 0 effectively turns off the Distortion circuit.
Using the EVB3’s Integrated Rotor Cabinet Emulation
The Hammond story can’t be fully told without discussing the rotor cabinets, manufactured
by Leslie. In fact, playing the B3 organ without a rotor cabinet is viewed as something of
a special effect these days.
The EVB3 not only simulates the speaker cabinet itself, but also allows you to change the
listening position by placing virtual “microphones in different locations.
Some of the speaker cabinet models are mathematically simulated, and others use an
actual recording of the spatial characteristics of the speaker. The latter is known as an
“impulse response.” Detailed information on impulse responses can be found in the Space
Designer section of the Logic Studio Effects Help.
If you’re unfamiliar with the concepts of the Leslie rotating speaker cabinets, see The
Leslie Cabinet.
Basic EVB3 Rotor Speaker Controls
The “basic” Leslie rotor parameters are available in both the closed and open lid interfaces
of the EVB3. These provide quick access to the Leslie speaker simulation.
The advanced rotor speaker controls are discussed in Advanced EVB3 Rotor Speaker
Controls.

On/Off button: This enables and disables the Leslie cabinet simulation.
Rotor Speed buttons: These switch the rotor speed in the following ways:
Chorale: Slow movement.
Tremolo: Fast movement.
