TREBLE: As with most guitar amplifiers, the TREBLE Control is the strongest of the three rotary tone controls. Its setting
on the STUDIO CALIBER determines the blend and strength of the MIDDLE and BASS Controls. Set high, it is the
dominant control, minimizing the amount of MID and BASS that would otherwise be
possible in the mix. Set low, the TREBLE becomes the recessive control and a warmer,
darker blend is produced. Dial with care. Subtle tweaking of this control tends to produce the
best results.

NOTE: The lower region of the MID Control determines midrange punch and boldness in lower gain sounds and a
smooth "vocal like" blend in high gain sounds. It can be very effective acting as a "cut through the band control" in certain
situations. Dial to taste, remembering that the setting of the TREBLE Control greatly effects this control’s strength.

MIDRANGE: Through daily tone dreaming, the "if-only" design dictum led to the dial-in-gain boost. In the STUDIO CALIBER
an over the top crunch sound was made possible by the inclusion of the RHYTHM Channels dual purpose MID Control.
From to about the taper is adjusted to act as a very effective MID Control. As you
increase the MID to and above, you will hear the lower Mids getting more pronounced
and fatter. When the Mid Control is set at about the MID leaves behind the old
notion of being a tone control and becomes a truly usuable gain control. This
upper range is a smokin’ addition to the RHYTHM Channel’s GAIN Control for all kinds of
higher gain rhythm sounds. Try the MID set high and the GAIN Control at about
6 for a cool blues solo sound. "Dime" the MID for a grinding crunch rhythm sound.
If this still isn’t crazy enough for you...Max the GAIN and TREBLE Controls and set the
PRESENCE Control to and plug into a MESA 4x12 with some Celestion Vintage
30’s or 25’s. This should be sufficently heinous for even the sickest crunch fiends. As
you can see, the versatility that this dual purpose Mid Control lends to the RHYTHM
Channel greatly expands its usefulness as both a clean and overdrive channel.

BASS: This control blends in the lower frequencies and its effectiveness, again, depends on the setting of the TREBLE Control.
It should be set with moderation, as extreme settings in either low or high directions can produce an unbalanced tone. Be
especially careful in higher Gain settings of either channel. Too much BASS will
cause a flabby unfocused sound that can’t be dialed out because excessive
BASS has been introduced to the pre-amp in the early stages. Try setting the
BASS to for clean sounds in the RHYTHM Channel and or below when
dialing up high gain overdriven sounds in this channel. In the LEAD Channel,
try setting the Bass somewhere between and .
