CARE AND MAINTENANCE
Use a soft, dry cloth for external cleaning. Avoid chemical
products, which may damage rubber and plastic parts.
This unit uses an internal long life potentiometer that con-
trols the sweep of the wah wah filter. It may eventually pre-
sent unexpected noises due to dust and dirt accumulation.
A “scraping” sound will become audible through your amp-
lifier. If you experience this problem, try cleaning the poten-
tiometer. Just remove the back aluminum cover for access.
Apply a fine spray of electronics contact cleaner with lubri-
cant directly inside the potentiometer. Move pedal back and
forth to ensure penetration of cleaner.
DO NOT USE
ALCOHOL or WD40
®
. If results are unsatisfactory, seek
authorized personnel for potentiometer replacement.

THE KILLER WAIL, AN OVERVIEW
A staple in the world of music since the ‘60s, the wah wah
effect was made popular by some of the most influential
guitar players in the world. Nostalgia, however, tends to
make us forget some of the shortcomings-- excessive
noise, tendency to be thin sounding with certain guitars/
pickups, and general quality of the mechanics.
The Killer Wail preserves the original circuit design and
overcomes its faults. Going a step further, we’ve incorpo-
rated new features to enhance its performance:
•Mode selector switch
extends the variety of curves.
•Humbucking Inductor:
custom wound and potted
inductor coil cancels noise and reduces microphonics
while faithfully reproducing the saturation and har-
monics of vintage wahs.
•Bypass switch
has an extra pole to remove the cir-
cuit load, which can muddy and weaken the signal.
Our goal is to provide 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.
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 incorporated Tech 21 and made his
invention commercially available to players and studios
around the world. His highly-acclaimed
SansAmp™
pioneered Tube Amplifier Emulation in professional appli-
cations for recording direct and performing live, and cre-
ated an entirely new category of signal processing. There
have since been many entries into this niche, yet SansAmp
maintains its reputation as the industry standard.
After developing a full line of SansAmp models, Tech 21
expanded its offerings to include effect pedals, as well as
”traditional” style amplifiers.
