DRIVE SWITCH:
Switch in to enable the extra 'Drive' tube stage. This gives you even more gain to play around with. (This
switch must be in the engaged position in order for the drive to be switched remotely via a foot switch.)
DRIVE:
This sets the amount of ‘Drive’ sound provided by the extra tube stage. This varies from subtle crunch to hi-gain lead
break sounds.
DRIVE LED:
This led will illuminate when the extra drive stage is switched in.
BASS, MIDDLE, TREBLE:
These are a traditional set of passive tone controls. Passive controls have the advantage of always
sounding musical at any of their settings mainly due to their unique interactive nature. This gives players a more natural set of tools to
create their ideal sound. (Try them all set at midway (5) as a good starting point)
PRESENCE:
An output stage tone control. This adjusts the high frequency response - it adjusts your sound from being dull to
giving it edge / sounding sparkly.
RESONANCE:
Adjusts level of Power Tube damping. This allows the player to adjust how tight the bass response is - this will be
dependent on what speaker cabinet used. The Resonance allows you to adjust the bass damping to your particular taste.
STANDBY:
Disconnects the HT supply from the Tubes whilst the heaters still keep them warm. This allows you to switch out of
standby and play without waiting for your amplifier to warm up. This is useful after you have sound checked and you are waiting to go
on stage - leave the amp in standby so its ready to go when performance time comes. Always switch off for short breaks when you
don’t want to wait for the tubes to warm up again.
POWER:
Main power switch for the unit. The GH50L features delay turn on circuitry to increase tube life, the HT supply to the
tubes gets switched on only after they have warmed up and are ready to go - approx 30 seconds.
(Always switch off and disconnect the power cord when not in use)
