(9) BOOST (not on 20MH)
Acts as an extension to the VOLUME control (#10). When depressed, this switch boosts the overall volume
level of the Lead channel. The volume BOOST may be selected independently or in conjunction with the
GAIN boost (#8). This feature can be controlled via the same optional remote dual latching footswitch
mentioned earlier.
NOTE: Activating this feature is comparable to turning up the VOLUME control, thus increasing loudness. It
has more apparent effect in the middle areas of the VOLUME controls range.
In the case of the ValveKing
GAIN (#8) is selected.
(10) VOLUME (not on 20MH)
Controls the overall output level of the Lead channel.
(11) BASS, MIDDLE AND TREBLE EQ
Passive tone controls that regulate the low, mid and high frequencies of the Lead channel. In the case of the

(12) REVERB
Controls the overall reverb level. Fully counterclockwise will be completely dry with no reverb, low settings
will produce subtle reverb and high settings will produce lush ambience. This feature can also be controlled
via a second optional remote dual latching footswitch.
(13) RESONANCE (ValveKing
This patented feature, available only from Peavey, is used to fine-tune the low-frequency response and
damping factor of the power amp section. At higher settings, the speakers are allowed to move more freely
at low frequencies, resulting in more apparent low end with slightly less signal clarity at maximum settings.
(14) PRESENCE (ValveKing
This control is used to fine-tune the high-frequency response and damping factor of the power amp section.
At higher settings, the speakers are allowed to move more freely at high frequencies, resulting in more
apparent high end.
(15) DAMPING (ValveKing
This control is used to fine-tune the overall response and damping factor of the power amp section. At
higher settings, the speakers are allowed to move more freely, resulting in more apparent low and high end.
Lower settings will produce a tighter sound.
(16) VARI-CLASS
This patented feature available only from Peavey is used to fine-tune the power sensitivity, response and
"break-up" of the power amp section of your ValveKing
results when the VARI-CLASS
point when setting this control. As the VARI-CLASS
half of the power tubes is progressively subtracted from the circuit, while the gain of the driver tube is
slowly increased. The driver's low-frequency response is also altered along with the gain, resulting in more
even-order harmonic distortion from your power amp, even at lower-than-stage-volume settings. Finally,
with the VARI-CLASS
amp section that operates and responds exactly like a true Class A power amp, driven by a real single-ended
high-gain tube stage.
This setting still allows the unused power tube(s) to draw idle current, thus retaining the efficiency of
the standard Class A/B topology. In this mode, power output is also reduced by as much as 60% versus
maximum rated power.
(17) MASTER VOLUME (ValveKing
Controls the overall output level of the amplifier on both channels. The tone and balance between the two
channels can be set by VOLUME (#3) and GAIN (#7), then the playing volume can be set as desired by the
MASTER VOLUME (#17).
