INTRODUCTION
SansAmp was designed and engineered to satisfy your critical ear. It is not a distortion pedal or fuzz box. Attempts have been made to recreate the unique,
full sound of various tube amplifiers in one convenient, compact unit you can
easily carry anywhere. But the technology has eluded designers and resulted in
products that continually disappoint musicians.
Uncompromising standards and ten years of research now bring this engineering feat to reality. SansAmp not only duplicates the warm, rich tones of tube
amps, the sounds are actually improved to be cleaner and more flexible (“Hot
Wired”) with less noise. SansAmp preserves the original sound of your guitar
so that your individual personality and style remain unaltered.
With SansAmp, you can plug directly into any recording console, stage amplification, stereo, or even into a set of headphones alone. SansAmp virtually eliminates all existing considerations of tube amplifiers without sacrificing any sound
quality.
THE HISTORY
Since an early age, I have been awed by the irony of high technology. Why, in
this age of ultra sophistication, do we still have to assemble a seemingly endless
chain of mechanical and electronic devices to produce a guitar or bass sound
suitable for recording and live performances?
To me, the whole process was like using a turbo jet engine to blow out a can-
dle....you have to assemble hot-rodded amps, speaker cabinets, microphones,
equalization, etc., to achieve an end result equivalent to a couple of millivolts of
signal! The standard method of miking amps and speakers is time consuming,
frustrating, inefficient, and expensive. Due to the nature of tube amps and the
many steps involved, it’s virtually impossible to quickly obtain a consistent
sound every time you set up. For years I wondered why couldn’t the sound of
an amplifier be created on an electronic level in a compact unit?
Based on my own needs as a guitarist and my extensive experience as a modifier and customizer of amplifiers, I set out to answer my own questions. Spanning
a ten-year period of research and development, I have probed stages of design
addressing the full character of sounds particular to various amplifiers (i.e.,
®
Marshall
microphones.
The end result is SansAmp --”sans” meaning “without” in French. By design,
SansAmp has extremely low noise, is compact and portable, and is able to
quickly and consistently reproduce a wide range of sounds for a variety of uses.
It is important to understand the nature and interaction of the controls on
SansAmp. It is not a device simplified to a few presets that makes all guitars,
pickup combinations and players sound the same. Much like a Moog® synthesizer, its programmability lets the user explore fine and important nuances within
the tube amp sound spectrum to achieve a personal voice.
The switches and knobs are designed to be interactive in a way that makes
sense; they affect each other enough to build a wide range of sounds, but they
are tailored to remain within the tube amp “vernacular” in order to be as useful and easy to use as possible. SansAmp was designed to recreate the natural
sound of tube amplifiers without effects. Signal processing (including distortion,
compression, etc.) can be added creatively to complement the sound of
SansAmp.
Historically, nothing has been able to match the sound of a tube amplifier --until
now. SansAmp stands alone as a tool that gives you the freedom to explore,
define and refine sound right at your fingertips. It is with great pride that I bring
you SansAmp in the hopes it will complement and contribute to the evolutionary process of your self expression.

GUIDE FOR INDIVIDUAL CONTROLS
INPUT SWITCH:
LEAD: Marshall®-style pre-amp sound, with mid-range and highs emphasized.
NORMAL: Mesa Boogie®-style pre-amp sound, with a basically flat EQ.
BASS: Fender®-style pre-amp sound (excellent for rhythm as well as bass).
CHARACTER CONTROLS:
#1.
Mid-Boost I
#2. Mid-Boost II
#3. Low Drive
#4. Clean Amp
#5. Bright Switch
#6. Vintage Tubes
#7. Speaker Edge
#8. Close Miking
Achieves various pre-amp EQ curves in the mid-range, for example:
#1 and #2 OFF = Brightest Sound
#1 ON = In-Between Sound
#2 ON = In-Between Sound
#1 and #2 ON = Fattest Sound
Achieves different pre-amp EQ curves on the low spectrum.
When ON, it has a flat frequency response.
When OFF, acts as High pass Filter. For fuller body, keep setting ON.
Cleans up overdrive. Excellent for achieving chunky rhythm sounds.
Adds brightness when Amp Drive is on lower settings. Best results
are when Amp Drive is half-way up, as there will be no effect when
Amp Drive is on full.
Final sound becomes a touch softer and mellower.
Adds extra presence to the final sound.
Duplicates the sound of a microphone being placed closely to the
speaker cabinet, and slightly boosts the bottom end.
IMPORTANT NOTE: The Character Controls were not designed to be
adjusted during live performances. They were developed for extra versatility to
give you total freedom of expression of your individual tonal taste. Once
desired programming is achieved, settings should remain constant. If used during
live performances, amplification should be set WITHOUT distortion.
GUIDE TO KNOB CONTROLS
PRESENCE DRIVE
Shapes pre-amp contours in the upper mid-range. For maximum crunch, set on
full.
AMP DRIVE
Shapes power amp contours. For heaviest distortion, set on full.
OUTPUT
Controls overall volume. Balance with Bypass signal for best sound. For headphones, insert jack half-way and boost Output.
HIGH
Balances final EQ. Compensates extra high-end of guitar amplifiers during live
use; suggest setting half-way or less. When recording direct in a studio, recommend setting be on full.
USING SANSAMP WITH EFFECTS
When using SansAmp with effects, remember that EQ can be placed before or
after SansAmp to achieve different results. Otherwise, place the following
effects:
BEFORE SansAmp: AFTER SansAmp:
Compression Chorus
Distortion Delay
Envelope Follower Harmonizer
Wah-wah Reverb
Special Note: SansAmp contains a F.E.T. buffer which improves the guitar signal
even in Bypass mode; your instrument will sound better through SansAmp even
when not using its sound-shaping capabilities.

OTHER INSTRUMENTS & APPLICATIONS
Be creative! SansAmp is not just for guitar. We encourage you to experiment
with other instruments, such as bass, keyboards, drums, sax, harmonica, vocals,
etc., and in other applications, such as in mixdowns to liven up existing tracks.
LIVE USE WITH GUITAR AMPLIFIERS
When using SansAmp in live performances with a guitar amplifier, it is advisable
to have Amp Drive at a lower setting to compensate the higher level of sustain
and overdrive associated with guitar amplifiers. The lower setting will also avoid
microphonic feedback. To equalize brightness of live amplification, it is suggested
to set High half-way or less.
ADVANTAGES
•Eliminates the need for an effects loop. Put effects between SansAmp and
amplifier input.
•Obtain a Vintage Hot-Wired Marshall

•”Channel switching.” You can use the Bypass switch on SansAmp to obtain a
clean sound.

FREQUENTLY ASKED QUESTIONS
1. I’m getting too much noise. What’s wrong? Check for pickup interference caused by lights, etc., by moving guitar. Single coil pickups are more likely to generate hum, and EMG-style active pickups can be hissier than humbuckers. With a mixing board, try a line input, if available, instead of a mic input.
2. Should I use my amp’s built-in distortion with SansAmp? Probably
not. Since the last distortion in the signal chain determines the sound, any additional distortion should be placed before SansAmp, taking care not to overload
SansAmp’s input. (This will not harm the unit, however it will adversely alter the
sound.) Use the guitar amplifier’s low-gain input, if available.
3. Why are SansAmp’s Character Switches so small? Primarily to keep
the unit compact. Larger switches would not only increase SansAmp’s size, but
they would also raise the cost and effect its reliability. Remember, this product
was not designed to have settings changed during live use. Hint: use the edge of
a guitar pick or pen cap to move the switches up or down.
4. Why isn’t the headphone output louder? SansAmp is designed to be
multi-purpose as well as compact. Therefore, the output serves a variety of
uses. For headphones, simply insert the stereo headphone jack approximately
half-way into the SansAmp output and you will get sound left and right. Then
boost the output to desired volume. Suggest using AKG K141 or comparable
headphones.
