Congratulations on your purchase of an SWR WorkingPro 12
combo amplifier! You now own the famous SWR tone, power,
clarity, and true full-range response that's made SWR the choice
of professionals for over twenty years. Your WorkingPro 12
combines the best SWR features:
• The famous preamp designed by original engineer Steve W.
Rabe
• Aural Enhancer™ and Active EQ controls
• Bass Intensifier™ circuit—simultaneously boosts and
compresses specific frequencies to add pure low-end
thickness to your bass sound
• New Wedge EQ specially designed for amp "tilt-back"
operation
A. INPUT— Plug your bass into this jack using a
shielded instrument cable.
B. INPUT PAD—Reduces input sensitivity to allow cleaner
response from high-output (above 1-Volt RMS) bass gui-
tars. Use the setting that sounds best!
NORMAL—Full input sensitivity
–10dB PAD—Lower input sensitivity
For active (pre-amplified) bass guitars: If you hear distor-
tion—even with -10dB INPUT PAD selected and a low
GAIN {D} (PREAMP CLIP not flashing)—check your guitar
battery.
C. MUTE—Disables the amplifier's audio outputs except
TUNER {T}, EFFECTS SEND {Q} and HEADPHONES {P} which
remain active. Use MUTE during: instrument changes,
tune-ups and when using headphones. The
cates when MUTE is engaged.

Since our founding in 1984, SWR has served one purpose—to
provide bass amplification products with professional quality,
tone, features and power delivery for players of all levels and
styles. We sincerely thank you for choosing SWR, and remain
committed to helping you Amplify Your Future™.
Read through this Owner's Manual before using your
WorkingPro amplifier to take advantage of the full potential of
your WorkingPro amplifier and to ensure the safe operation of
your investment!
D. GAIN—Preamp volume control. Use GAIN primarily to
control signal distortion, then use MASTER Volume {K} to
adjust the loudness of the amplifier. GAIN also sets the
EFFECTS SEND {Q} output level, allowing you to match
the input sensitivity of your effects unit. Use the PREAMP
CLIP LED to find the desired GAIN setting:
PREAMP CLIP—Indicates when the preamp is being
overdriven (clipping), causing signal distortion. Adjust
GAIN until PREAMP CLIP flashes slightly at the peak
input levels from your instrument to get the maximum
power with the least distortion from the WorkingPro.
NOTE: Preamp clipping is not harmful to the amplifier
and can be used for effect.
