TECH 21, THE COMPANY

Tech 21 was formed by a guitarist possessing the unusual combination of a trained ear and
electronics expertise. In 1989, B.Andrew Barta made his invention commercially available
to players and studios around the world. His highly-acclaimed

SansAmp™ pioneered

Tube Amplifier Emulation in professional applications for recording direct and performing
live, and created an entirely new category of signal processing.There have since been many
entries into this niche, yet SansAmp continues to maintain its reputation as the industry
standard.

With a full line of SansAmp models,Tech 21 also offers effect pedals and MIDI products, as
well as “traditional” style amplifiers for guitar and bass. Each product is thoughtfully and
respectfully designed by B.Andrew Barta himself with the player in mind. Our goal is to
provide you with flexible, versatile tools to cultivate, control,refine and redefine your own
individual sound.Tech 21 takes great pride in delivering consistent quality sound, studio to
studio, club to club, arena to arena.

PRODUCT OVERVIEW

The Boost R.V.B. is an analog reverb emulator pedal that uniquely incorporates a clean
boost function for up to 9dB of additional volume.With boost and reverb in a single pedal,
your solos will jump out with greater dimension.

This pedal is designed with user-tweakable,“lo-fi” analog technology. By manipulating the
controls, you can infuse degrees of warmth and life characteristic of vintage reverbs.The
circuitry intentionally injects the inherent imperfections of vintage reverbs, which is what
makes them so seductive and nostalgic.A single,
a full sweep of reverb. Rumble contours the low end of the reverb.The Mix, Feedback,
Tone and Level controls are 100% analog for warm, organic sounds.The Boost R.V.B.
enables you to explore and custom tailor such reverb styles as spring, plate and natural
room/hall ambiance.

As with each Tech 21 product, the controls are designed to give you the flexibility to
obtain your desired sound. It is our hope that the Boost R.V.B. will be a useful tool for
stimulating your creativity and, ultimately, providing the inspiration to play your best.

continuously-variable Time control provides

SIGNAL LEVEL TO INPUT/CONNECTIONS

The Boost R.V.B. is designed to accommodate instrument level signals to the Input, such as the
output of a guitar, the output of distortion pedals, etc. For normal operation, signal level to
should be close to that of a standard electric guitar (approx -10dBm / 250mV).

NOTE: Some amplifier effects loops are line level,which will cause the Boost R.V.B. to distort. It
will also compress the signal and reduce the output.The same may hold true for mixing boards.
Therefore, you may need to obtain a level matching transformer.

Be aware that line level signals will not damage the Boost R.V.B., however the resulting sound may
not be particularly desirable.

GUIDE TO CONTROLS

TIME

Controls the decay time of the reverb from short to long.This single, continuously-variable con­trol provides a smooth, full sweep to easily dial in the exact amount of reverb with one turn of
the knob.

TONE

100% analog shelving filter of 6dB per octave. Effects the high-end of the reverb signal.At maxi­mum (5 o’clock), it has no effect. As you reduce the setting, it will decrease the high-end to round
off the signal and add warmth.
Tone Tips: Higher settings will yield a brighter, snappier,more in-your-face presence. Lower set-
tings will be darker, more distant. In general, and for a more natural sound, the reverb should be
slightly darker than your guitar signal or they may clash with each other.

FEEDBACK

100% analog circuit. Feeds back the reverb signal to the input to increase the amount of reverb.
Different from the Time control, Feedback is primarily useful to achieve various spring reverb
effects.We recommend using sparingly, as too much can cause oscillation or undesirable feedback.
Feedback tips: For optimal spring reverb, slowly increase Feedback just to the point of oscilla­tion, then reduce until it stops. For wild special effects, experiment with Feedback on the brink -­or past-- the point of oscillation.

MIX

100% analog circuit.Adjusts the ratio of direct and reverb signal.While most reverb pedals pro­vide a maximum 50/50 mix ratio via a level control,the Tech 21 Mix control offers a sweep from
100% dry to 100% wet.This gives you more flexibility when you want to run through a parallel
effects loop without annoying phase cancellation, and to make the reverb signal louder than the
direct signal for special effect.

THE INS AND OUTS

1/4” INPUT: 1megOhm high impedance input, same as traditional tube amps.Also switches

battery power on/off.To avoid battery drain, unplug when unit is not in use.

1/4” OUTPUT: 1kOhm low impedance output drives long cables without loss of signal

integrity, even in bypass.

RUMBLE

Controls the amount of low-end content of the signal.At maximum (5 o’clock), there is no effect.
Decreasing the setting from max will remove low end to make it tighter, which is useful for spring
and plate reverb settings in particular.

LEVEL / BOOST

100% analog circuit.Adjusts the overall output level. Increasing from unity gain (12 o’clock) pro­vides additional boost, up to 9dB.
Level tip: If you have a 100% wet signal going through a parallel effects loop, use the Level to
adjust the mix of dry and effected signal.
