Treble Mid Bass - Mesa/Boogie LoneStar Amplifier Owner's Manual

FRONT PANEL: Controls & Features
TREBLE:
As in most tube guitar amplifiers, the TREBLE control ( in both channels of your LONE STAR ) is the most powerful
of the rotary controls and is next in line only to the GAIN control as a shaping tool. Because it is first in the signal path of the tone
controls - and from here the Middle and Bass receive their signal - it is by far the dominant tone control. For this reason the setting of
the TREBLE control is very important for equal representation of the three frequency regions to appear at their respective controls.

especially effective in CHANNEL 1 and Channel 2 with the DRIVE bypassed. When doing so, use the PRESENCE control to roll off
some of the more than ample top end for a more compressed feel and fatter voice. As you might surmise, the BASS control's effective-
ness will be reduced, so you may have to run a much higher setting than you are used to seeing to achieve a balance.
MID:
The MID control is responsible for the blend of midrange frequencies in the mix and though its effect is not as dramatic as
that of the TREBLE control, it plays an integral part in achieving any sound in your LONE STAR. It is capable of changing the feel
dramatically as it blends in a group of frequencies that tend to soften or stiffen the way a sound feels to play.
Most players tend to lean in the direction of lower MID control settings ( 7:00 - 11:00 ) where a scoop in this region produces girth ( by
letting the Bass become a little more dominant ) and a lack of punch lends a more compressed, even feel to the strings and therefore

BASS:
The BASS control in your new LONE STAR works similarly in both channels in that it determines the amount of low fre-
quencies present in a sound. However, the style of lows it mixes in changes from channel to channel. Like the MID control, it falls in
line signal-wise after the TREBLE control and the same scheme applies. When the TREBLE control is set high, the effectiveness of after after the TREBLE control and the same scheme applies. When the TREBLE control is set high, the effectiveness of

less apparent resistance to the pick. As the MID control is increased, ( 11:30 - 1:30
) the sound is rounded-out and filled-in with a focused mid attack appearing rather
quickly. As you would guess, the feel starts to change - becoming more resistant.
Above this region the MID control could be used to compensate for either weaker
pick-ups or for times when a specific deficiency is produced by either an extremely

For the most balanced sound and a balance of power between the three rotary tone controls,
try to use the TREBLE control in its middle ranges.This scenario produces nearly equal repre-

for further tweaking.

the TREBLE control where ample top end is mixed in and yet enough signal
is still passed on to the MIDDLE and BASS controls.
