The amplifier produces
random noises even if no
guitar is plugged in.
Check if this happens on both channels (this information can be
crucial for the service department). Unplug the guitar and switch to
the distorted channel – check if the noise disappears when you
turn down the Lead Gain:
•
If yes, unplug the power cable from the amplifier, wait for
the tubes to cool down, unscrew the rear grate and
exchange the tube in the V1 position with any other tube. If
the problem disappears, keep this tube configuration.
•
If the noise is still present, check if it disappears when you
turn down the Lead Volume. If yes, unplug the amplifier
from the power socket, wait for the tubes to cool down,
unscrew the rear grate and exchange V2 for V3 or V4. If the
noise persists, turn the Master down. If the noise persists
after you have taken these measures, contact your Laboga
Dealer and tell about your observations
Footswitch won’t change
channels.
Unplug the cable from the Footswitch and try to change channels
manually;
•
If channels can be changed manually, replace the footswitch
cable. A stereo cable is preferable. A mono cable will work
as well, but the Master cannot be changed by footswitch
and only Master 2 is active.
If the problem persists, contact authorized Laboga service or any
Laboga retailer.
