5. CHANNEL 2 VOLUME: – The Volume control lets you determine the amount of signal that progresses through to the power
amp section. The Volume control should be used in conjunction with the Channel 2 Drive control and the Master Output control
in order to get the desired tone out of the amp.
6. LEAD EQ CONTROLS: These are a traditional set of passive tone controls. Passive controls have the advantage of always –
sounding musical at any of their settings, due to their unique interactive nature. This gives the player a more natural set of tools to
shape their ideal sound. Set these to midway (12 O’clock) as a good starting point.
MID-SHIFT: Pulling on the MID control knob will shift the response of the control, this lowers the frequency range of the mid
control to give a tighter sound.
7. TONE: – This Tone control works in a similar fashion to the Tone control you probably have on your guitar except that it
uniquely works at the other end of the amplification chain. This has the ability to not only control the overall top end response but
also reduce upper harmonics on the output stage and preamplifier overdrive sounds. This will give you bright cutting sounds at
high settings and smooth rounded sounds at lower settings. Midway (
) is a good starting point. 12 O’clock
The Tone control depends greatly on the speaker cabinet connected to the amplifier.
8. MASTER OUTPUT: – The Master Output control determines how “open” the output section is allowed to run. Dial in a low
setting and the output section is wound back and the overall listening level of the amplifier is reduced. Dial the Master Output fully
open and the output section of the amp is now running at full tilt. Experiment with the Master Output and the Channel 2 volume
controls set in different relationships. Experimenting with these controls is the key to getting the best tone out of your amp.
Try the sample settings on page 10 as a starting point to your ideal tone
9. REVERB: – Controls the level of the built in Laney-designed digital reverb.
PULL FOCUS: Focus more on the guitar tone as opposed to external influences, (room, fret noise etc) –
10. STANDBY SWITCH: – Disconnects the main HT voltage from the tubes but keeps the tubes warm so that they are ready
to play instantly. Switch for short breaks when you don't want to wait for the tubes to warm up again. With the switch in the 1
position, the amp is in play mode, while 0 allows the amp to warm up.
STANDBY LAMP: – This will illuminate when the amplifier is in play mode.
11. POWER SWITCH: – Main power switch for the unit. Tube amplifiers take between 30 seconds to 2 minutes to warm up
and be ready to play after switching on, this is normal. Use in conjunction with the standby switch to prolong tube life. To turn on,
flip the switch to 1.
POWER LAMP: – This will illuminate when the power switch is operated, indicating the presence of mains power within the amplifier.
