Laney LC15-110 Operating Instructions Manual page 11

4 BRIGHT: Adds brightness and life to the treble frequencies of your guitar when on the clean channel. The switch has more
effect at low Clean Volume control settings. Use in conjunction with the Treble and Tone controls for optimum performance.
5
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls for the clean channel. 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).
6 VOLUME Sets how loud the clean channel is. Try cranking it up a little to drive the power tubes harder for that real retro :
sound and feel that only a quality tube amplifier can deliver. Now use your guitar volume to control the amount of distortion.
7
TONE: The 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 end 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 (5) is a good starting point)
8 REVERB: Controls how loud the built in reverb sounds.
9 POWER LED: This led will be lit when the amplifier is switched on.
10 POWER: Main power switch for the unit. Tube amplifiers take between 30 seconds and 2 minutes to warm up and be ready
to play after switching on, this is normal.
(Always switch off and disconnect the power cord when not in use)
