OWNER’S MANUAL

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 directl y 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 candle....you have to assem-

ble 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®, Fender®,Mesa Boogie®,etc.) in conjunction with speakers and 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 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: For sound of Marshall®-style pre-amps,with mid-range and highs emphasized.
NORMAL: For sound of Mesa Boogie®-style pre-amps,with a basically flat EQ.
BASS: For sound of Fender®-style pre-amps.Excellent for rhythm as well as bass guitar.

CHARACTER CONTROLS:

#1. Mid-Boost I
#2. Mid-Boost II

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

#3. Low Driv e

Achieves different pre-amp EQ curves on the low spectrum.
When ON,it has a flat frequency response.
When OFF, it acts as a High pass Filter. For fuller body, keep setting ON.

#4. Clean Amp

Cleans up overdrive. Excellent for achieving chunky rhythm sounds.

#5. Bright Switch

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 AmpDrive is on full.

#6. Vinta ge Tubes

Final sound becomes a touch softer and mellower.

#7. Speaker Edg e

Adds extra presence to the final sound.

#8. Close Miking

Duplicates the sound of a microphone being placed closely to the speaker cabinet,and slightly
boosts the bottom end.

IMPOR TANT NOTE: The Character Controls of this unit were not designed to be adjusted during live
performances.They have been 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 WITHOUTdistortion.

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.
