PSA-1 Controls
Use the eight knobs to dial in your desired tone
or effect.
Pre-Amp Determines the input sensitivity and
pre-amp distortion. Increasing the setting pro-
duces an effect similar to putting a clean booster
pedal ahead of a tube amp, overdriving the first
stage. For cleaner sounds, use settings below the
unity-gain point.
Buzz Controls low frequency break up and over-
drive. Boost the effect by turning clockwise from
the center point indicated by the arrows. As you
increase towards maximum, the sound becomes
(you guessed it) buzzy, with added harmonic
content. For increased clarity and definition
when using distortion, position the knob at its
midpoint or towards minimum.
Punch Sets midrange break up and overdrive.
Decreasing from the center produces a softer,
“Fender”-style break up. Increasing the setting
produces a harder, heavier distortion. At maxi-
mum, it produces a sound similar to a wah pedal
at mid-boost position placed in front of a Mar-
shall amp.
Crunch Brings out upper harmonic content and,
on guitars, pick attack. For cleaner sounds or
smoother high end, decrease as needed.
Drive Increases the amount of power amp distor-
tion. Power amp distortion is associated with
the “Vintage Marshall” sound—using SansAmp,
you can produce the effect even at low levels.
Low Provides a tone control specially tuned for
maximum musicality when used to EQ low fre-
quencies on instruments. Boost or cut by ±12 dB
by turning from the center point indicated by
the arrows.
High Boosts or cuts high frequencies ±12 dB.
Level Boosts or cuts the overall gain to re-estab-
lish unity after adding distortion or equalizing
the signal.
Tips and Tricks
Peace and Unity
A little known fact: The arrows in the SansAmp
controls indicate the unity-gain position.
Louder and Cleaner
For best results, don’t set the Pre-Amp level
lower than unity gain when the Drive knob is at
9 o’clock or higher. However, if you want a crys-
tal-clear sound and the Drive control is already
near minimum, decrease Pre-Amp to further re-
move distortion.
Pre-Amp Versus Drive
To create varying types of overdrive, vary Pre-
Amp in relation to Drive. A high Pre-Amp set-
ting emphasizes pre-amp distortion (see
“Mark 1” preset), while high Drive settings em-
phasize power amp distortion (see “Plexi” pre-
set).
