LABOGA – The Beast 30 Plus
5. Drive Gain
Gain control for the distorted channel.
With a little value you can obtain fuzz
effect or soft overdrive. By turning the
gain right, distortion is rising until
reaching the high gain. Note that for
guitars with Humbucker pick-ups or any
high output signal pick-up, it is
possible, that turning the knob to the
right, does not make more distortion,
but more noise. It is designed that way,
to allow low signal guitars also to reach
a high-gain.
HINT: To find the best volume balance
between channels, use Clean Gain
knob; in lower Drive Gain settings, it's
better to work in lower Clean Gain
settings and the other way around.
6. Channel selection
It allows to change between clean-
crunch or drive.
It works only when the Jack is
unplugged from the Footswitch socket.
When pressed the drive channel is on –
then the red light is on.
7. Bass
Adjusts the low-frequency for Drive
channel only
8. Mid. Switch
It changes the frequencies of the EQ
stack. Although it affect mostly middle
frequencies, it changes a bit also a
bottom and high. It works then as it
would be two different EQ circuits, but
switchable.
9. Treble
Adjusts the high-frequency tone for
Drive channel only.
HINT:
Set all EQ potentiometers in a
12.00 o’clock position, then adjust
them individually to get the best tone.
Remember, that the frequencies of
each controller are related to each
other, the change of one influences the
other.
10. Master Volume
Master volume control.
HINT: Apart from controlling the
volume, it influences saturation of the
power tubes. Maximum setting force
power tubes to work at saturation and
therefore a power section distortion
appear.
11. Stand By / Power selector switch
In the middle position (“0”), the
amplifier is at standby. Switching to
any other position, sends the plate
voltage to the tubes – in these
positions the amplifier plays.
To work in 30W mode, switch to “I”.
To work in 15W mode, switch to “II”.
IMPORTANT: Before turning the amp
in, you should check, if switch is in the
“0” position. Then wait about 1 min.
before switching to either “I”, or “II”
mode.
HINT: Both settings makes the circuit
working with different plate voltages –
the 15W mode - with lower voltage.
Therefore if you normally operate at
low volumes, or use just headphones
use the 15W mode to prolong longer
life span.
12. Power switch
The switch turns the mains power
supply on and off. The amplifier is off
when the switch is in position “0” –
then the red indicator lamp is not
illuminated.
The amplifier is on when the switch is
in position “I” – the switch is
illuminated in red.
IMPORTANT: Before turning the
amplifier on, always make sure that
the Standby switch is in position “0” –
it will extend the life span of the tubes.
The amplifier should be turned on in
the following way: first, turn on the
Power switch and wait about 1 minute.
Next, you can turn the Standby on.
Turning off the amplifier works the
other way around. First, turn the
Standby on, then wait about 1 minute,
afterwords you can turn the Power off.
