especially if you're looking for a uniquely expressive rhythm texture.Typically, a
humbucking equipped guitar already has a lot o bass and midrange. If you are seeking
clean comping or rhythm tones, having the notch pulled out (250Hz) will allow for more
string definition and headroom. Conversely, a single coil equipped guitar has less mids
and may need the fat sound of the notch switch pushed in (550Hz).
Bass
The "chunk" and support that form the backbone of your tone come from this control.
Also, when using a singled coil guitar for a jazz or bebop tone, this control will add the
needed fatness to the lower strings.
Master (with Pull Boost switch)
Channel 2 has a special EQ circuit that works in conjunction with the distortion circuit to
sweeten the tone. Therefore, the Master knob's effect goes beyond loudness control.
Try it with different Volume and Middle settings to adjust the amount of "singing" and
"grit." The Boost, activated by pulling the Master knob (or pressing the switch on the FS-
7 Footswitch), is a sweet-sounding boost characterized by a more subtle effect on the
harmonics than Channel 1's Boost control while adding sustain. The Ch.2 Boost helps
to drive the power amp, and the best description of its influence over the tone is that it
thickens it.
Reverb
This control allows for the excellent "Hammond 6 Spring Long Pan" Reverb to be
enjoyed. This is a "Parallel" effect, and is adjustable for intensity up to 50%. Adjust to
taste.
Focus
This control is another RIVERA exclusive that actually lets you change the speaker's
response characteristics, from tight to loose. The effect can give closed-back cabinets a
sound more akin to an open one, and vice-versa, plus you can "custom blend" the
amount of hardness your final sound has. New to Rivera amps, first unveiled on Quiana
is a new "Pull Warm". By pulling this control, the bottom end response of the power amp
section changes as well as the high end, giving a sweet contoured tone. The Focus and
Presence controls will also be modified in their sweep, increasing their effectiveness.
Presence
The Presence control is incorporated as a vital part of the power amp section. Think of it
as a final brightness control after all the EQ, distortion and effects.
Standby
By turning the Power on and the Standby off (the down position, labeled with a "0"), you
can warm up the amplifier before applying full voltage to the Preamp and power output
tubes. This prolongs tube life. Using the Standby switch when you're taking a break also
helps to extend the tubes' life, plus it keeps the amp constantly at the ready. Just flip the
Standby switch to the up ("I") position, and you're ready to play.
Power
This is your main power switch. The on position is indicated by the light being
illuminated. The off position is marked by the "0" on the switch. Before turning the amp
