Pull Deep; Mid; Treble - Mesa/Boogie M3 Carbine Owner's Manual

FrONT PANeL CONTrOLS:
This type of broad band, active rotary control makes it possible to achieve bass characteristics far beyond that of a conventional
passive type control. It can increase the low end to an almost absurd level and with a flick of the wrist, dip it to near transistor radio
skinniness. Needless to say, with any control this powerful a certain amount of finesse must be applied to achieve musical results.

PULL DEEP:

The M3 CARBINE features a pull shift for the BASS control that allows you to choose between two different
regions of low end and affects how the control will react.
subtle enhancement of the super-high frequencies is added to create a round, breathing cushion of air the whole band can ride. Be
sure to check out this setting for three-piece Rock or Blues combos and playing R & B styles where you need to ad juice to thumbing
part.

MID:

This is the only passive style control in the string of rotary tone controls. This scheme was chosen for its inherently musical
blend and for the way the passive style midrange control, with its wide spread and smooth taper, fills in the holes. Unlike the BASS,

TREBLE:

The TREBLE is also an active shelving style control like that found in the BASS and again, it was chosen for its ability to
When the control is pushed in (normal) the bass frequencies are higher and a cut-off is employed so
that below a certain point, sub-low frequencies are not part of the mix. This results in a tighter, faster
feeling response that is more articulate and will stand out and be heard in a live stage environment.
This also works well for recording scenarios where the Bass part needs to sync-up with a complex kick
drum line or anytime you need a defined, punchy sound that won't get lost as the layers of other parts
get applied.
PULL DEEP (control pulled out) allows the entire range of low frequencies to pass and fill in the curves
creating a warm, rich sound that is foundational for smaller groups. Along with these deeper lows, a
this control is a boost only, and while it can competently remove this broad spectrum of midrange from
the mix, it cannot provide the extreme attenuation of an active style control.
You will find, as we did, that this control works amazingly well for shaping the midrange frequencies with
a natural earthiness and character that is a perfect counterpart to its neighbors. It is hard to find bad
sounds with this more forgiving control as it seems to give you just enough and no more.
We opted for the tried and true passive style midrange control because it's been working great in all of
our amplifiers for decades. It's hard to improve on a classic.
radically shape the upper harmonic region. Like the BASS, it also has a center Q point with harmonics
above and below responding in harmony as it is dialed for either cut or boost.
As the control is increased past 12:00, it produces a 6db per octave rise in gain starting at 723Hz until
+20db is reached. From this point, gain remains constant at +20db for all frequencies above 723Hz all
the way out to 20Khz. This scheme lends a sweetness of sound while retaining all the necessary cut
and focus associated with a traditional passive TREBLE control. As this control is dialed below 12:00, it
begins a 6db per octave cut from 3.2Khz to the shelving point at 723Hz, where it continues to attenuate
