TREBLE - Adjusts the high frequency response. At lower settings of this control the tone will be
warmer and smoother. As you turn this control up the highs become more prominent and
aggressive adding gain to the signal as well. This control is very interactive with the Bright switch,
Middle control, and Deep switch. In the full counter-clockwise position, high frequencies are
bypassed to ground. In the full clockwise position, high frequencies are allowed to pass to the next
gain stage.
MID Switch - Boosts the midrange frequency response.
MIDDLE - Adjusts the midrange response. At low settings of this control the tone will be “scooped”
of midrange response, emphasizing the highs and lows. As this control is turned up, the midrange
frequencies are increased. This creates the “body” of your guitar’s tone and is very critical to both
the tonality, feel and overall response of the amplifier. Higher settings of this control also help your
tone to cut through the mix in both a live band situation and when playing the amp outdoors.
In the full clockwise position, mid-range frequencies are allowed to pass to the next gain stage.
DEEP Switch - Boosts the lower bass frequencies. This low frequency contour switch also shifts
the emphasis from the upper bass frequencies to the lower bass frequencies which helps smooth
out and clarify the midrange response.
BASS - Adjusts the bass response. In the full counter-clockwise position, low frequencies are cut
and the response of the treble and mid-range controls is greatly reduced. As this control is turned
up, the bass frequencies are increased and allowed to pass to the next gain stage.
BYPASS Switch - Referred to as Tone Stack Bypass, this switch bypasses the Bass, Middle, and
Treble controls effectively turning them up all the way and increasing both the volume and
perceived mid-range response. The Bright, Mid, and Deep switches remain active in the Bypass
mode. This function is also foot switchable. To enable footswitch control of this function, the switch
must be in the down position.
LEAD GAIN - Adjusts the input level (gain) of the lead channel. Although we refer to this as the
“lead channel” it is actually an additional “cascading” gain stage in the amp’s circuit driven by the
FET, EQ1/2, Gain, Bass, Middle, Treble, Bright, Mid, Deep, and Bypass controls. It has been
meticulously designed to add a very dynamic and touch responsive overdrive capability to the
amplifier. The setting of the amp’s controls has a direct effect on the gain, tone and feel of the lead
channel. Experimentation is key to striking the desired balance between the clean and lead
modes.
LEAD Switch - This switch engages the lead channel. This function is also foot switchable.
To enable footswitch control of this function, the switch must be in the down position.
LEAD MASTER - Adjusts the output level of the lead channel. Use this control to set the desired
volume of the lead mode in relation to the clean mode.
