FRONT PANEL CONTROLS

VOLUME: Controls the volume of the amplifier. Experiment with different combinations of the Drive and Volume controls 

to achieve different sounds. Reducing the Drive while increasing the Volume will result in a warm, open, overdriven sound 

as the power amp is driven harder, while reducing the Volume and increasing the Drive will give a tighter, more modern 

sound with more distortion. Once set, try using your guitar's volume controls to interactively adjust tone and distortion 

levels. Use the low power input socket to push the output stage hard (settings 7-10) at quiet practice levels. Set the Drive 

control to 0 and turn up the volume control for a clean setting.

POWER LED: This will illuminate when the power switch is operated, indicating the presence of mains power within the 

amplifier.

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 (0) is a good starting point.  Both the Tone and Dynamics 

controls depend greatly on the speaker cabinet connected to the amplifier.

REVERB: Controls the level of the built in Laney-designed digital reverb.

DYNAMICS: This allows control over the response of the amplifier at lower frequencies. Turning this control clockwise 

gives a looser low end, while lower settings provide a tighter response. The optimum setting is dependant both on the 

speaker cabinet and the volume level being used.
