Chapter 98: Using Eleven 545
Tone
Tone controls let you shape the highs, mids and
lows of the amp sound. Electric guitar pickups
tend to have a strong low-mid emphasis and lit-
tle high frequency response, often producing a
mid-range heavy sound that requires some tre-
ble boost. The response and interaction of the
tone controls are unique to each amp.
Bass
The Bass control determines the amount of low
end in the amp tone. The response of this con-
trol in some models is linked to the setting of the
Treble control. The default setting is 5.0. Bass
range is from 0 to 10.
Middle
The Middle control determines the mid-range
strength in lower gain sounds. With high gain
amp models, the Middle control has a more dra-
matic effect and can noticeably shape the sound
of the amp at both the minimum and extreme
settings. The default setting is 5.0. The Middle
range is from 0 to 10.
Treble
In most amp models, the Treble control is the
strongest of the three tone controls. Its setting
determines the blend and strength of the Bass
and Middle controls. When Treble is set to
higher values, it becomes the dominant tone
control, minimizing the effect of Bass and Mid-
dle controls. When Treble is set to lower values,
the Bass and Middle have more effect, making
for a darker amp tone. The default setting is 5.0.
The Treble range is from 0 to 10.
Presence
The Presence control provides a small amount of
boost at frequencies above the treble control.
Presence is applied at the end of each amp model
pre-amp stage, acting as a global brightness con-
trol that is independent of other tone controls.
The default setting is 3.0. The Presence range is
from 0 to 10.
Master
The Master control sets the output volume of the
pre-amp, acting as a gain control for the power
amplifier. In a standard master-volume guitar
amp, as the Master volume is increased more
power tube distortion is produced. The default
setting is 5.0. Master range is from 0 to 10.
Tremolo
Tremolo is achieved through the use of ampli-
tude modulation, multiplying the amplitude of
the pre-amp output by a waveform of lower fre-
quency. Tremolo is not available on all amps.
Tremolo Speed The Speed control sets the rate
of the Tremolo effect. The Tremolo Speed LED
pulses at the rate of Tremolo Speed. The default
setting is 5.0.
Tremolo Depth The Depth controls the amount
of the Tremolo effect. The default setting for
this control is 0.0, which is equivalent to off.
Some amp models call the Tremolo Depth con-
trol Intensity.
Some might assume a Master volume knob
capable of silencing the amp completely. Not
so. Use the Output knob (in the Master sec-
tion) to silence the output of the plug-in. Use
Master volume for tone and distortion.
Eleven does not support Tempo Sync.
