Stampa la paginaThe BOOST stage gain is set to roll off some of the low end and low mid tone while adding a slight bit of punch, which may feel
like compression. We feel this will yield the best gain tone (which would typically be used for soloing).
At very low settings (the knob turned to the "9:00" position or lower), the BOOST will actually cut the underlying tone. Further
clockwise after the 9:00 position, the GAIN stage will be additive to the underlying gain of the CRUNCH channel.
REVERB – The reverb control allows you to increase the "echo", or reverb, by turning it clockwise as indicated by the graphic.
TREBLE, MID & BASS – Use these controls to shape your sound. Start by setting the controls at the midpoint for all three
controls, and then experiment with making minor adjustments to each control, progressively, until the preferred sound is
achieved.
Section 5
This section is where you will find the controls for the DELAY and TREMOLO effects.
Delay Effect
VOL – Use this control to raise or lower the volume level of the DELAY effect.
TIME – Use this control to set the time between delays. Turning the control clockwise increases the DELAY time, while turning
the control counterclockwise decreases the delay time.
REPEAT – Use this control to set the number of repeats the DELAY effect produces. Turning the control clockwise increases the
number of repeats, while turning the control counterclockwise decreases the number of repeats heard in the DELAY effect.
Tremolo Effect
SPEED – Use this control to vary the speed of the tremolo effect. Turning the knob clockwise increases the speed, turning it
counterclockwise decreases the speed.
DEPTH – Use this control to set the depth of the tremolo effect. Turning the knob clockwise increases the depth, turning it
counterclockwise decreases the depth.
Section 6
This section is where you will find the controls for the MASTER volume controls and the STANDBY ("STBY") switch.
MASTER 1 – Use this control to raise or lower the overall volume level of the amplifier.
MASTER 2 – Use this control to raise or lower the overall volume level of the amplifier when the footswitch for the MASTER 2
volume is pressed.
If you've never had an amplifier with two master volumes, think of them as follows. You have the opportunity to set two master
volume levels on the amplifier, and to switch between those levels simply by using the footswitch. For example, you might want
a boost tone that not only changes its tone via the boost gain control, but also has a louder volume as well. This is why we set
the last two switches on the footswitch closer together, allowing them to be enabled together at the same time.
STBY – Tube amps need to be warmed up when they're initially turned on. Putting the amp in standby (STBY) and then
switching the power switch 'On', allows the amp to be turned on but keeps full voltage from reaching the power tubes until
they've had sufficient time to warm up. This approach goes a long way towards protecting the power tubes and will
substantively prolong their useful life.
It is also recommended that your amplifier be turned off in the reverse order, setting standby switch to 'STBY' and then turning
the power switch to 'Off'.
